Section allows you to create an API key belonging to your user. This API key will have the same permissions as your user has at the time of creation. When your user is deleted, this key will persist.
You can create an api with your user by making the following request:
curl -u username:password -XPOST -d '{"query":"mutation { createUserAPIToken}"}' https://aperture.section.io/new/authorized/graphql_api/query
Where you should replace username and password with your section username/password for basic authentication.
Use your API Key by adding it to your requests in the Section-Token header.
curl -H "Section-Token: API-KEY-HERE" aperture.section.io/api/v1
