Ingest a document

Receives an external ID and value form which identifies the document type and forwards the request onto the API endpoint that manages that type of content. Supports Projects, Categories, and Contacts. See the API Reference for these types for parameter options. Only URL safe characters are supported for this endpoint, even if URL encoding is used. To work with external IDs that contain other characters please consider using an encoding method that uses URL safe characters like the Base64 URL variant.
