easyVerein API (v2.0)

Quick start

• Base URL: https://easyverein.com/api/v2.0
• Auth header: Authorization: Bearer <API_KEY>
• Tokens expire after 30 days; refresh via GET /api/v2.0/refresh-token when tokenRefreshNeeded appears in response headers.
• Rate limit: 100 requests/min.

Use the OpenAPI spec

Read the full spec when you need endpoint details or schemas:

• references/openapi-v2.json

This file contains all endpoints, parameters, request bodies, responses, and tags. Use it to:

• list endpoints by tag (e.g., member, contact-details, invoice)
• inspect request body schemas
• find actions and sub-endpoints

Common patterns

• Pagination: ?limit= (default 5, max 100)
• Field selection: ?query={field,relation{subfield}}
• Excluding fields: ?query={-field}
• Bulk operations: bulk-create / bulk-update (supported by select endpoints)

Example cURL (template)

curl -s \
  -H "Authorization: Bearer $EASYVEREIN_TOKEN" \
  -H "Content-Type: application/json" \
  "https://easyverein.com/api/v2.0/member?limit=10"

Member creation flow (important)

1. Create contact-details first.
2. Then create member with emailOrUserName and contactDetails reference.

Notes

• Files must be uploaded via PATCH with Content-Disposition header.
• Use refresh-token to rotate tokens; old token becomes invalid immediately.
