Steps
Use the vendor's dedicated file-upload method rather than the generic CRUD add/change calls — e.g., Fiix's uploadFile RPC call rather than WorkOrder add/change.
Supply a sourceInfo/sourceType (e.g., WORK_ORDER_INFO) and the target record's ID string so the platform attaches the file to the right work order.
Send the file content as part of the multipart/form-style payload the SDK or documented endpoint expects, not as a JSON string field.
Confirm the file's association by re-fetching the work order/asset and checking its attachment/file list.
Check platform-specific supported file types and size limits before upload (e.g., ServiceTitan restricts uploads to a fixed list of file extensions).
Known gotchas
Some FSM/CMMS APIs don't support deleting or modifying attachments once uploaded (confirmed for ServiceTitan) — treat uploads as append-only.
File upload is often a separate mechanism from the main object CRUD API (different content-type, different endpoint) — don't expect to embed binary data in a normal JSON create call.
Supported file-type lists are platform-specific and enforced server-side; uploading an unsupported extension can fail without a clear error in some third-party integrations.
