Authentication methods and fields
Pick one of these under Authentication Method on the connection wizard's Authentication step. This table is generated from the integration catalog, so it always matches what the form actually asks for.
| Method | Required | Optional |
|---|---|---|
| Oauth2 / App Token - Sandbox | — | — |
| Oauth2 / App Token | — | — |
Manage this integration with Terraform
Connections for this integration can be managed as code with the Relyance Terraform provider. Non-secret fields go in auth.params; secret fields go in auth.secrets_wo, which is write-only — never stored in Terraform state. Rotate secrets by bumping auth.secrets_wo_version.
OAuth (browser authorization) — Oauth2 / App Token - Sandbox
The OAuth (browser authorization) — Oauth2 / App Token - Sandbox method uses a browser authorization flow, so the connection is created in the Relyance app. Manage it in Terraform afterwards by importing it (terraform import relyance_integration_connection.example sendoso/<connection_id>) or reading it with the relyance_integration_connection data source.
