Make API Shell Connection Workflow

Make API Shell + Connection Workflow

Use this skill for one specific workflow family:

• discover the correct Make app and app-specific API-call module
• reuse or build a reusable shell scenario with StartSubscenario, one app API-call module, and ReturnData
• reuse an existing suitable connection or create the connection request needed by that shell
• patch the shell with the selected connection once authorization is complete
• run the scenario and use it as a generic SaaS retrieval transport for email, CRM, tickets, and similar systems

This skill is primarily about provisioning and shell construction. Treat business retrieval as a second phase that starts only after the connection is ready and the shell has been validated against current workspace metadata.

The generic shell described here is an API transport wrapper, not business logic. It should behave like a reusable API endpoint for any SaaS app that Make can front, including email, CRM, ticketing, support, marketing, or task systems.

Known Make module id: the Make Code module is "module": "code:ExecuteCode".

Quick routing

Read the file that matches the current task:

Fresh-agent operating sequence

When a fresh agent gets a request such as "get my unread emails", "pull my open CRM leads", or "fetch my Jira tickets", the default operating sequence is:

1. Resolve the provider anchor.
   • email: Gmail vs Outlook vs other
   • CRM: HubSpot vs Salesforce vs other
   • ticketing: Jira vs Zendesk vs Linear vs other
2. Resolve the target account, mailbox, workspace, project, or queue if the request is ambiguous.
3. Resolve the active Make zone, organization, and team.
4. Resolve the provider app deterministically. GET /api/v2/imt/apps ignores search, limit, and scoredSearch and always returns the full ~4k-app catalog, so never rely on server-side search. Match locally instead: search a curated top-apps catalog first (in helper environments, search_apps(query=...) does this); only when nothing matches there, fetch the full catalog once and filter it client-side, case-insensitively, over name and label. All query words score; without an exact phrase match the first query word must hit for a candidate to count, and the first ranked result is the recommended app.
   • Only Make-verified apps and the organization's own custom/SDK apps may be auto-selected. Community apps (communityApp-*) are excluded from matching; custom apps (catalog prefix app#*) are allowed. Authoritative check: GET /api/v2/imt/apps-meta lists all verified and custom apps available to the organization (custom-app names appear there without the app# prefix). Builtin utility pseudo-apps (builtin, util, gateway, regexp) are not SaaS providers and must never surface as search results. If the provider only exists as a community app, treat it as "no app" and build a generic HTTP fallback shell instead — see HTTP Fallback Shells.
5. Inspect the chosen app with GET /api/v2/imt/apps/{appName}/{version} and record the exact API-call module slug and both connection type layers.
6. Reuse an existing suitable connection only after verifying details and liveness: GET /api/v2/connections/{connectionId} plus POST /api/v2/connections/{connectionId}/test.
7. Reuse an existing shell only when reusing an existing suitable connection. If a new connection must be created, create a new shell for that new connection instead of patching an old shell onto a newly authorized account.
8. Only if no suitable connection exists, create a credential request.
9. After the connection decision is settled, create or patch the shell according to the reuse rule above and verify that the shell can run.
10. Run the narrowest possible retrieval request first through the API-call shell.
11. Expand into list/search -> detail -> normalization only after the first shell run proves the path works.
12. If no Make app exists for the provider at all, build a generic HTTP fallback shell with http:MakeRequest instead of giving up — see HTTP Fallback Shells.

The agent should not jump straight from "user wants SaaS data" to "create a new connection" or "call a direct SDK" without walking this sequence.

Input-resolution gates

Before provisioning or retrieval, explicitly resolve these inputs:

• provider anchor
• target account identity if multiple accounts or mailboxes are possible
• intended credential-request recipient if it may differ from the current token owner
• Make zone, organization, and team

If one of those items is missing and cannot be discovered safely, stop and ask only for that exact missing item.

Core rules

1. Never guess the API-call module name. Discover it from current Make metadata.
2. Treat example apps such as Gmail, Outlook, or HubSpot as illustrations, not as universal defaults.
3. Keep the two type layers separate:
   • scenario/module connection parameter type
   • connection listing or credential request type
4. Prefer reuse before creation:
   • existing suitable connection before new credential request
   • existing shell scenario only when reusing an existing suitable connection
   • a newly authorized connection must get a newly created shell
5. Do not route business retrieval to native Make search/list/get modules. For this workflow family, always retrieve through the Make app's API-call shell.
6. Ask for confirmation before writing into an existing live scenario or replacing a connection mapping.
7. Keep public examples sanitized. Do not include real names, user IDs, team IDs, organization IDs, tenant-specific hosts, or claims that a single private workspace proves a universal rule.
8. Use a clean base URL variable in examples. For public examples, default to https://us1.make.com and keep placeholders generic. Do not mention we.make.com in public examples unless the current user explicitly provides or requests that zone. Valid zones can be eu1, eu2, us1, us2, or we, and if the user provides a custom zone or BASE_URL, accept it.
9. Separate four phases explicitly:
   • provider and app resolution
   • connection provisioning
   • shell provisioning
   • retrieval execution and output normalization
10. Do not assume the generic three-module blueprint is automatically activatable for every app. Before activation, compare the middle module metadata with a real current blueprint or module export for the same app and version in the active workspace.
11. For the generic API shell contract that uses scenario-service:ReturnData with ExpectDataAny, the final mapper must return the app module response body as data: {{MIDDLE_API_MODULE_ID.body}}.
12. In the generic example blueprint in this skill the middle API-call module id is 3, so the example mapper is data: {{3.body}}. If the real blueprint uses different module ids, use the real middle module id instead. For example, a Make UI export may use StartSubscenario 2, API-call module 5, and ReturnData 4, so the correct mapper is data: {{5.body}}.
13. Never replace that shell-contract default with {{MIDDLE_API_MODULE_ID}} or {{MIDDLE_API_MODULE_ID.data}} just because the full bundle looks tempting. The shell is meant to return the API response body, not the entire Make module bundle.
14. Still inspect a real execution bundle for validation, but use that to confirm that body contains the intended payload or error object — not to redefine the generic shell contract.
15. Resolve the active workspace zone before any team-scoped call. GET /api/v2/users/me and GET /api/v2/imt/apps/... can succeed on multiple zones, while GET /api/v2/connections?teamId=... or scenario endpoints on the wrong zone can fail with 403 Permission denied.
16. For the REST /api/v2/connections endpoint, filter with type=... or type[]=.... Do not assume query parameters such as accountName=... are honored just because an MCP tool uses accountName terminology.
17. Do not ask the user to paste raw OAuth secrets, API keys, or passwords into chat. Use a credential request whenever a new connection must be created. Pick the path by recipient: for the current Make user, the self-service endpoints (actions/create, actions/create-by-credentials) work on a wide range of plans; only requesting credentials from a different person (requests/v2) is the Enterprise/Partner feature gated by license.credentialRequests (see Connection Requests, "Choose the request path by recipient first"). When no request path works, guide the user through creating the connection in the scenario editor instead. In all flows state the exact credential paste format (Bearer prefix or raw key) — never assume the user knows it.
18. If the user request is ambiguous, resolve the concrete provider and account first; if it is already explicit, do not ask again.
19. If the Module 2 request method is PUT, PATCH, or DELETE, warn explicitly before execution. Treat those methods as mutating live SaaS operations, not passive retrieval.
20. Do not assume StartSubscenario.metadata.interface is enough for scenario runs. After creating or updating an on-demand shell, explicitly set the scenario-level interface with /api/v2/scenarios/{scenarioId}/interface and verify it before the first run.
21. Treat /api/v2/scenarios/{scenarioId}/run as the standard execution path for this shell family. Pass the business payload under data with keys that match the scenario interface exactly, and prefer responsive: true for validation runs.
22. Expose query parameters as a first-class shell input named qs. Use qs for provider API query parameters such as Gmail search options, Drive fields, Drive q, Graph $select, pagination, or supportsAllDrives. If a caller provides a query string in path, normalize it into qs before running the shell.
23. When moving blueprints between Make UI exports and Make scenario create/update APIs, normalize shape deliberately: UI/export artifacts may store the flow at subflows[0].flow, while scenario create/update payloads require a top-level flow. Do not send a raw UI export to create/update without normalization.
24. Shell reuse is app-specific, not just provider-family-specific. A shell built around one app module should not be repointed to another app module just because both belong to the same vendor suite.
25. Before reusing any existing connection or a shell that points to an existing connection, call Make's connection verification API: POST /api/v2/connections/{connectionId}/test. A response with verified: true is the liveness proof. A stale Credential Request status does not override a verified connection. Liveness is not proof that the provider will authorize every path, method, or scope; provider authorization is proven only by a successful shell run for the intended operation. On provider auth or scope errors, use the Authorization Repair Playbook.
26. When resuming after user authorization, reuse the saved Credential Request requestId; inspect the request, then list and verify connections. Do not create a new Credential Request while an active request for the same app/account is still being resolved.
27. Treat a future expire timestamp as valid. Treat only a past expiry, revoked connection, failed verification, or provider auth error as invalid.

App binding and connection-family matrix

The shell pattern is generic, but each actual shell is bound to one discovered Make app module.

Do not treat “Google” or “Microsoft” as a single interchangeable connection family. In Make, app families often split by product surface.

Common examples:

Rules that follow from this:

• Reuse a shell only when the discovered app, module slug, version, and connection family still match.
• Reuse a connection only when the account identity and scopes still fit the requested operation.
• If a new connection is authorized for a different account or connection family, create a new shell for it instead of silently repointing an old shell.

When in doubt, inspect the exact app metadata and existing connection detail instead of inferring compatibility from the vendor name.

Standard shell shape

The reusable shell has exactly three modules:

1. scenario-service:StartSubscenario
2. one app-specific Make API-call module discovered from metadata
3. scenario-service:ReturnData

Expose these shell inputs through StartSubscenario:

• path
• method
• header
• qs
• body

Use the discovered middle module as the only app-specific part of the shell.

Generic shell contract

This shell is a generic API endpoint wrapper.

It receives:

• path
• method
• header
• qs
• body

It forwards those values into the app-specific Make API-call module.

Default retrieval should use GET. Treat PUT, PATCH, and DELETE as write/destructive methods and require explicit user confirmation before running them.

It returns exactly one thing:

• the response body from the app-specific Make API-call module

Therefore the shell contract is:

{
  "data": "{{MIDDLE_API_MODULE_ID.body}}"
}

In this skill's generic example blueprint, MIDDLE_API_MODULE_ID is 3, so the example value is {{3.body}}. In a real Make export, always inspect the module ids and use the actual API-call module id.

That contract is generic across SaaS providers. It applies whether the middle module fronts Gmail, Outlook, HubSpot, Jira, or another provider-specific Make API-call module.

The shell should not try to return:

• the whole Make bundle {{3}}
• a guessed nested field such as {{3.data}}
• transport metadata mixed together with the body

The shell is transport only. Business interpretation happens later.

Two-phase operating model

Phase A: provisioning

Complete these steps first:

1. identify the provider and exact Make app
2. discover the exact app version and module slug
3. determine both connection type layers
4. look for an existing suitable connection for the correct account identity and scope
5. verify candidate connections with POST /api/v2/connections/{connectionId}/test
6. look for an existing shell scenario that already fits the contract for that verified connection
7. create or resolve the credential request only if reuse failed
8. create a new shell if a new connection was created, or patch an existing shell only when reusing an existing connection
9. verify that the shell runs with the chosen connection

Deliverable at the end of Phase A:

• a connection-ready API-call shell scenario

Phase B: retrieval

Only after Phase A succeeds:

1. configure the retrieval call through the API-call shell
2. run a narrow validation query or lookup
3. inspect the real output bundle shape
4. keep ReturnData fixed as the generic shell contract and update only downstream normalization if needed
5. rerun and verify the user-facing payload

Do not treat a successful credential request as proof that the retrieval stage is already solved.

Important:

• the generic three-module API shell remains the only retrieval transport in this workflow family
• keep the shell contract fixed as data: {{MIDDLE_API_MODULE_ID.body}} where MIDDLE_API_MODULE_ID is the actual app API-call module id in the blueprint
• do not switch to native retrieval/search/list modules as a fallback or optimization
• if authorization fails because an existing connection is expired or invalid, do not try to re-auth that connection in place; go through the credential-request path and then create a new shell for the new connection

Interface-and-run rule

For on-demand shells, treat interface provisioning as a separate deployment step:

1. create or update the scenario blueprint
2. explicitly set /api/v2/scenarios/{scenarioId}/interface
3. verify the interface shape before the first run
4. only then call /api/v2/scenarios/{scenarioId}/run

Use a run payload shaped like:

{
  "data": {
    "path": "...",
    "method": "GET",
    "header": [],
    "qs": [],
    "body": null
  },
  "responsive": true
}

The key names under data must match the scenario interface exactly. If the interface was never explicitly set, run can reject the call even when the StartSubscenario module itself contains interface metadata.

Body-handling compatibility rule

Keep the generic shell contract stable, but do not assume every provider module tolerates an empty or null body the same way.

Observed-safe pattern:

• write-capable shells can expose and map body
• read-heavy shells may need to omit the Module 2 body mapper entirely when the provider module serializes empty payloads badly on GET or DELETE

If a provider-specific Make API-call module fails only when body is present-but-empty, prefer one of these patterns:

• a read shell without a body mapper
• a write shell with a body mapper
• two separate shells when the provider behavior differs between read and write paths

Do not change ReturnData for this. This is a Module 2 request-shape compatibility issue, not a shell-output-contract issue.

Response behavior

When using this skill:

• first summarize the discovered app, version, exact API-call module name, and both connection type layers
• explicitly state how the provider was resolved: user statement, existing Make artifacts, or Make app-catalog lookup
• explicitly say whether the shell is being reused or newly created
• explicitly say whether the connection is being reused or newly requested
• explicitly state which phase you are in: provisioning or retrieval
• when retrieval begins, state the API-call plan: list/search path, any follow-up detail paths, and normalization plan
• if a new connection was created, explicitly state that a new shell was created for it
• if the request started as a business ask such as email, CRM, or tickets, state the business target and the exact API path pattern you chose
• explicitly label any assumptions
• keep write-operation prompts brief and concrete
• if Module 2 is about to run a PUT, PATCH, or DELETE, stop and warn before execution
• if activation fails or ReturnData looks wrong, stop calling the flow complete and report the exact failing phase
• if sharing publicly, rewrite examples with placeholders and neutral labels before finalizing
