Run npx skillmds@latest add dvcrn/didit-sessions in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

What does the Didit Sessions skill do?

Integrate Didit Session & Workflow APIs — the central hub for managing verification sessions. Use when the user wants to create a verification session, set up a KYC workflow, create a session with a workflow_id, retrieve session results, get session decisions, list sessions, delete sessions, update session status, approve or decline sessions, request resubmission, generate PDF reports, share sessions between partners, import shared sessions, add or remove users from blocklist, manage blocked faces/documents/phones/emails, handle webhooks, or implement any end-to-end verification flow using Didit. Covers 11 API endpoints: create, retrieve, list, delete, update-status, generate-pdf, share, import-shared, blocklist-add, blocklist-remove, blocklist-list. It is listed under Docs & Writing on SkillMD.

Is Didit Sessions safe to use?

This skill has not completed SkillMD's automated safety review yet. Independent scanners report: SkillSpector: CAUTION, Skill Scanner: PASS. Capability flags: makes network calls, reads secrets. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Didit Session & Workflow APIs

Overview

Sessions are the core unit of Didit verification. Every verification starts by creating a session linked to a workflow (configured in Console). The workflow defines what checks run (ID, liveness, AML, etc.) and the decision logic.

Base URL: https://verification.didit.me/v3

Session lifecycle:

Create Session → User verifies at URL → Receive webhook/poll decision → Optionally update status

Rate limits: 300 req/min per method. Session creation: 600 req/min. Decision polling: 100 req/min. On 429: check Retry-After header, use exponential backoff.

API Reference: https://docs.didit.me/reference/create-session-verification-sessions

Authentication

All requests require x-api-key header. Get your key from Didit Business Console → API & Webhooks.

Session Statuses

Status	Description	Terminal
`Not Started`	Created, user hasn't begun	No
`In Progress`	User is completing verification	No
`In Review`	Needs manual review	No
`Approved`	Verification successful	Yes
`Declined`	Verification failed	Yes
`Abandoned`	User left without completing	Yes
`Expired`	Session expired (default: 7 days)	Yes
`Resubmitted`	Steps sent back for resubmission	No

Workflow Types

Workflows are created in the Business Console (UI only, not via API). Each has a unique workflow_id.

Template	Starts With	Use Case
KYC	ID Verification (OCR)	Full identity onboarding
Adaptive Age Verification	Selfie age estimation	Age-gated services (auto-fallback to ID if borderline)
Biometric Authentication	Liveness detection	Re-verify returning users (pass `portrait_image`)
Address Verification	Proof of Address	Residential address validation
Questionnaire	Custom questionnaire	Structured attestations and documents

Two build modes:

Simple Mode: Toggle features on/off from a template
Advanced Mode: Visual node-based graph builder with conditional branches, parallel paths, action automation

Available features in workflows: ID Verification, Liveness, Face Match, NFC, AML Screening, Phone Verification, Email Verification, Proof of Address, Database Validation, IP Analysis, Age Estimation, Questionnaire.

Common Workflows

Basic KYC Flow

1. POST /v3/session/ → create session with KYC workflow_id, get URL
2. Redirect user to session URL
3. Listen for webhook OR poll GET /v3/session/{id}/decision/
4. "Approved"  → user verified
   "Declined"  → check decision, optionally resubmit
   "In Review" → manual review or auto-decide via API

Programmatic Review + Blocklist

1. Receive webhook: status "In Review"
2. GET /v3/session/{id}/decision/ → inspect all results
3. Apply business logic
4. If fraud: PATCH → Declined + POST /v3/blocklist/add/ (block all entities)
   If legit: PATCH → Approved

B2B KYC Sharing

Service X:
1. POST /v3/session/{id}/share/ → get share_token
2. Transmit token to Service Y via backend

Service Y:
3. POST /v3/session/import-shared/ → import with trust_review=true
4. Session imported instantly with original status

Biometric Re-Authentication

1. Retrieve portrait_image from user's initial approved session
2. POST /v3/session/ → biometric auth workflow + portrait_image
3. User takes selfie → system matches against portrait
4. "Approved" → identity re-confirmed
