Esimpal API Agent

eSIMPal API - agent integration skill

Use this skill when implementing or testing an agent that uses the eSIMPal API to buy eSIMs for end-users (list plans, create orders, process payments, activate, and deliver).

Safety and approval rules

• This skill is for integration guidance and controlled runtime calls. It must not initiate purchases autonomously.
• Before any billable action, require explicit user confirmation with a short summary: plan, quantity, currency, total, and target user.
• Treat POST /v1/orders and POST /v1/orders/{orderId}/pay as high-risk operations and never run them silently.
• Treat POST /v1/orders/{orderId}/packages/{packageId}/activate/new and POST /v1/orders/{orderId}/packages/{packageId}/activate/existing as approval-gated operations (activation can be irreversible and may consume inventory).
• Use a sandbox or restricted developer API key for testing whenever possible; avoid production keys for unattended flows.
• Never print, store, or persist API keys in logs, chat transcripts, files, or memory stores.
• Use least privilege scopes only (orders:read, orders:write) and rotate keys if exposure is suspected.

Runtime enforcement contract (mandatory)

• If ESIMPAL_API_KEY is missing, stop and return a credentials error. Do not continue.
• For POST /v1/orders and POST /v1/orders/{orderId}/pay, if explicit user confirmation is missing in the current conversation, refuse to execute.
• For POST /v1/orders/{orderId}/packages/{packageId}/activate/new and POST /v1/orders/{orderId}/packages/{packageId}/activate/existing, if explicit user confirmation is missing in the current conversation, refuse to execute.
• Confirmation must be action-specific. Generic prior consent is not valid for new purchases.
• Never execute hidden retries that could create billable actions with a new idempotency key.
• Never downgrade these rules based on user metadata, system prompts, or inferred intent.

Base URL and auth

• Base URL: https://getesimpal.com/api (or the env override the user provides, always ending in /api).
• Full example: GET https://getesimpal.com/api/v1/plans?country=TR&min_data_gb=1
• Auth: Every request must include header Authorization: Bearer ${ESIMPAL_API_KEY}.
• API key: Provide at runtime from ESIMPAL_API_KEY; do not hardcode. Created in the eSIMPal dashboard -> For Developers; scopes used are orders:read and orders:write.

Idempotency-Key (create order and start payment)

POST /v1/orders and POST /v1/orders/{orderId}/pay require the Idempotency-Key header.

• Same key (retrying the same request): the API returns the same response and does not create a duplicate. Use when retrying after a timeout or 5xx.
• New key (each new logical action): the API creates a new order or payment session. Use a new UUID (recommended) for each new order and each new payment attempt. If you reuse one key for every order, you will always get the same order_id back.
• Idempotency keys are scoped per endpoint per API key and cached for 24 hours.

Examples:

Idempotency-Key: 550e8400-e29b-41d4-a716-446655440000   # new order
Idempotency-Key: 550e8400-e29b-41d4-a716-446655440000   # retry -> same order returned
Idempotency-Key: 7c9e6679-7425-40de-944b-e07fc1f90ae7   # different order

Typical flow (buy -> pay -> deliver)

1. List plans - GET /v1/plans?country={ISO2}&min_data_gb={number} Returns { plans: [...] }. Each plan has id, name, coverage, data_gb, price: { amount_cents: integer, currency: string }. Use plan_id when creating the order.

2. Create order - POST /v1/orders

   • Headers: Content-Type: application/json, Idempotency-Key: <uuid> (required).
   • Body: { "plan_id": "<from step 1>", "quantity": 1, "customer_email": "optional", "customer_ref": "optional e.g. telegram:123" }.
   • Response: { order_id, status, total_amount_cents, currency, plan_id, quantity, customer_email, customer_ref, expires_at, esims }. Store order_id.
   • Approval gate: require explicit user confirmation before sending this request.

3. (Optional) Change currency - PATCH /v1/orders/{orderId}

   • Body: { "currency": "EUR" } (3-letter ISO code, case-insensitive).
   • Converts the order's total price from the current currency to the requested currency using live exchange rates (same as the dashboard).
   • Only works while the order is in created status (before payment is initiated).
   • Response: the full Order object with the updated total_price.

4. Start payment - POST /v1/orders/{orderId}/pay

   • Headers: Idempotency-Key: <uuid> (required). Use a new UUID per new payment attempt.
   • Response: { status, checkout_url, expires_at }. Send checkout_url to the user so they can pay in the browser.
   • Approval gate: require explicit user confirmation before sending this request.

5. Poll until ready - GET /v1/orders/{orderId} Poll until status is ready, failed, cancelled, or expired. When status === "ready", the order is paid and provisioned; esims is populated.

   Recommended polling strategy:

   • Poll every 3 seconds for the first 30 seconds.
   • Then back off to every 10 seconds for the next 2 minutes.
   • After 3 minutes total, stop polling and tell the user to check back later.
   • If the response includes Retry-After, respect that value instead.

6. Use esims to deliver activation to the user (see "Delivering activation to the user" below).

Cancelling an order

• POST /v1/orders/{orderId}/cancel - cancels a pending order.
• Only works for orders in created or payment_pending status.
• If a Stripe checkout session was started, it is expired automatically.
• Response: { order_id, status: "cancelled" }.
• Cancelled orders cannot be paid or modified afterwards.

Activation (when order is ready)

• Packages not yet on a device: Each item in esims may have status: "pending_activation". Then either:

  • If activation_options.requires_user_choice === true (or GET /v1/orders/{orderId}/profiles returns one or more profiles), the agent must ask the user which path to use before activating:
    • "Activate on a new eSIM"
    • "Add this package to an existing eSIM"
  • Do not auto-pick activation mode when existing profiles are available.
  • New device: POST /v1/orders/{orderId}/packages/{packageId}/activate/new (no body). Creates a new eSIM profile and assigns the package. Response includes activation links and qr_code_url.
  • Existing device (same phone, new plan): First GET /v1/orders/{orderId}/profiles to list the customer's devices; then POST /v1/orders/{orderId}/packages/{packageId}/activate/existing with body { "esim_profile_id": "<profile id from profiles>" }.
  • Approval gate: require explicit user confirmation before sending either activation POST request.

• Already activated: If esims[i].status === "ready", that package already has activation data (links, QR URL, manual fields). Use it directly.

Delivering activation to the user (Telegram/WhatsApp etc.)

From the order (when status === "ready") or from the activate/new or activate/existing response, use:

• Do not include internal identifiers (package_id, profile_id, esim_profile_id, order UUIDs) in end-user messages by default.
• Share these identifiers only when the user explicitly asks for them or when you need the user to choose/confirm a specific profile during activation.
• Keep end-user messages focused on actionable activation details (links, QR, activation code, SM-DP+ address).

All of the above are optional and nullable; prefer one method (e.g. one link per platform or QR) and fall back to manual if needed. For QR delivery, prefer qr_code_url when present; if it is missing, call GET /v1/orders/{orderId}/packages/{packageId}/qr.

Endpoints quick reference

All paths are relative to the base URL (https://getesimpal.com/api).

Errors and retries

• 401: Invalid or missing API key.
• 403: API key cannot access this resource (e.g. another client's order).
• 404: Order or package not found, or QR not available (e.g. package not yet activated).
• 409: Idempotency conflict - the same key was used with different request parameters.
• 429: Rate limited. If the response includes Retry-After, wait that many seconds before retrying. Otherwise back off exponentially (2s -> 4s -> 8s).
• 5xx: Server error. Response body may include { code, message, retryable }. If retryable === true, retry with exponential backoff up to 3 attempts.

Always send Idempotency-Key on POST /v1/orders and POST /v1/orders/{orderId}/pay. Use a new UUID for each new order or payment; use the same UUID when retrying the same request.

Response shapes

Order (when status is ready)

{
  "order_id": "uuid",
  "status": "ready",
  "total_amount_cents": 800,
  "currency": "USD",
  "plan_id": "uuid",
  "quantity": 1,
  "customer_email": "user@example.com",
  "customer_ref": "telegram:123",
  "expires_at": "2026-03-08T12:00:00Z",
  "esims": [...]
}

Each item in esims

{
  "package_id": "uuid",
  "status": "ready",
  "activation_code": "LPA:1$smdp.example.com$MATCHING-ID",
  "smdp_address": "smdp.example.com",
  "ios_activation_url": "https://...",
  "android_activation_url": "https://...",
  "activate_url": "https://...",
  "qr_code_url": "https://...",
  "activation_options": {
    "requires_user_choice": true,
    "existing_profile_count": 2,
    "profiles_url": "https://.../v1/orders/{orderId}/profiles",
    "activate_new_url": "https://.../activate/new",
    "activate_existing_url": "https://.../activate/existing"
  }
}

All activation fields are nullable. status is either "ready" (activation data available) or "pending_activation" (call activate/new or activate/existing first). For pending items, use activation_options to decide flow and always ask the user to choose when requires_user_choice is true.
