Hi @Manpreet_Wasan! Would these docs be helpful here?
https://docs.retool.com/queries/guides/api-requests#form-data
https://docs.retool.com/queries/guides/files#rest-api-queries
https://community.retool.com/t/uploading-files-fails-with-the-new-components/7106/26
And do you know what your API expects in terms of file data structure (e.g. binary or form or something else)?
