With the release of CerteroX v9, the API now supports both READ and WRITE functionality. The attached guide provides basic instruction on using the API.
API capabilities by version
What the API supports depends on your Certero version. Please check yours before integrating.
Certero v9 onwards Read & write-back. Everything in v8, plus write-back for User-Defined Fields (UDFs) and User-Defined Assets (UDAs) only — create and update them via the API.
Certero v8 Read-only. Query and export data only. Nothing can be written back to Certero through the API.
