Steps
To upload a file attachment, send POST {api-domain}/crm/{version}/{module_api_name}/{record_id}/Attachments as multipart/form-data with the file in a file form field.
A single Attachments call can add either a file or a link, not both in the same request.
To add a note, send POST {api-domain}/crm/v8/Notes or POST {api-domain}/crm/v8/{module_name}/{record_id}/Notes with Note_Content (required) and optional Note_Title.
For the module-scoped Notes path, also identify the parent module and record via Parent_Id.
Confirm success via the HTTP 201 response for note creation.
Known gotchas
Attachment uploads require both the module-specific scope (e.g. ZohoCRM.modules.attachments) and the relevant module scope together.
Attachments and links cannot be combined in a single upload call — send separate requests for each.
