Skip to main content
This page provides code examples for common API use cases. All examples use environment variables for credentials — set them once and every example is copy-paste ready. For full request/response schemas, refer to each endpoint’s API reference page.

​
Setup

Set these environment variables before running any example: 
# Required: your service user API key (starts with cog_)
export DEVIN_API_KEY="cog_your_key_here"

# Optional: your organization ID (org-scoped service users can omit this)
export DEVIN_ORG_ID="your_org_id"
Organization service users don’t need DEVIN_ORG_ID — the API auto-resolves it from the credential. You can omit {org_id} from URLs entirely.

​
curl Examples

These examples work directly in your terminal after setting the environment variables above. 
curl -X POST "https://api.devin.ai/v3/organizations/sessions" \
  -H "Authorization: Bearer $DEVIN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt": "Create a Python script that analyzes CSV data"}'

curl "https://api.devin.ai/v3/organizations/sessions" \
  -H "Authorization: Bearer $DEVIN_API_KEY"

export SESSION_ID="your_session_id"

curl -X POST "https://api.devin.ai/v3/organizations/sessions/$SESSION_ID/messages" \
  -H "Authorization: Bearer $DEVIN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"message": "Please also add unit tests"}'

curl -X POST "https://api.devin.ai/v3/organizations/knowledge/notes" \
  -H "Authorization: Bearer $DEVIN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Coding standards",
    "trigger_description": "When writing code in this repo",
    "body": "Use TypeScript strict mode. Follow the existing code style."
  }'

curl "https://api.devin.ai/v3/enterprise/organizations" \
  -H "Authorization: Bearer $DEVIN_API_KEY"

# Uses Unix timestamps — example: Jan 1 to Jan 31, 2025
curl "https://api.devin.ai/v3/enterprise/consumption/daily?time_after=1735689600&time_before=1738368000" \
