Transfer a file chunk

POST/file/transfer/upload/Via 360: POST https://partner.quantri360.com/v1/tiktok_business/file/transfer/upload/

Write endpoint — changes data on TikTok Business. The key must be created with "Allow write API calls" ticked, otherwise you get 403 write_not_allowed. Every call is logged.

Description

Use this endpoint to transfer a file chunk. You need to segment your file to chunks based on the start_offset and end_offset values in the response of the /file/start/upload/ endpoint.

When the start_offset value is equal to the end_offset value returned in the response of this endpoint, the last chunk has been uploaded. Then you can call /file/finish/upload/ to finish the upload.
