Steps
Request Tessitura REST API access and documentation through your organization's Tessitura account rep — API Help pages are gated to registered developers, not published on a public doc site.
Obtain the four credential components: username, group ID, location, and password, which Tessitura combines for HTTP Basic Auth.
Format the Basic Auth string as username:group:location:password (colon-delimited) before base64-encoding it into the Authorization header.
Confirm which hosted TessituraService base URL your organization uses (each Tessitura customer runs its own instance, e.g. https://<org>.example/TessituraService).
Validate credentials against a low-risk read endpoint before building further integration logic.
Known gotchas
Tessitura API documentation is gated behind developer registration managed by your organization's Tessitura account — there is no single public reference URL for all customers.
Each Tessitura customer hosts its own TessituraService instance with its own base URL, so credentials and endpoints from one organization's docs won't work against another's.
A malformed delimiter in the composite username:group:location:password string is a common source of silent authentication failures.
