How do I connect a custom integration to the Endless GraphQL API?

Send HTTP POST requests to the GraphQL endpoint shown with your integration, using its access token and your company ID or handle.

HeaderValue
Content-Typeapplication/json
X-EC-Access-TokenYour integration’s access token, without a Bearer prefix
X-Company-IdYour Endless company ID or handle

The production endpoint is https://api.endlesscommerce.com/graphql. Test it with placeholder values replaced in your own trusted environment:

curl --request POST \
  --url https://api.endlesscommerce.com/graphql \
  --header 'Content-Type: application/json' \
  --header 'X-EC-Access-Token: YOUR_ACCESS_TOKEN' \
  --header 'X-Company-Id: YOUR_COMPANY_ID' \
  --data '{"query":"query ConnectionCheck { __typename }"}'

A successful response contains:

{"data":{"__typename":"Query"}}

This checks the endpoint and basic request structure. Test a query for the records you need as well; the connection check does not confirm that a particular operation or company dataset is accessible.

Use the API reference for current queries, mutations, arguments, and response types. See custom integration credentials and rotation and handling API responses.
