Cross-Cutting Reference
Diagnose Stuck Media Buys
Use API evidence and the customer troubleshooting workflow to understand a media buy that is not progressing.
Begin with the media buy’s current phase, latest failure, approval state, and
source or seller evidence. Preserve structured error codes and recovery fields;
do not infer a successful transition from an HTTP or MCP transport success.
The troubleshooting procedure is shared with people operating the same buy in
Interchange. It explains each lifecycle checkpoint, the evidence to collect,
and when support needs to become involved.
