I’ve been attempting to send a file to Telegram’s Bot API using a curl command. In my approach, I included specific form fields and headers to attach the document, yet I received a response stating that no file was provided. I reviewed the sendDocument method details in the Telegram documentation but still couldn’t pinpoint the issue. Could someone help identify the error in my command or the parameter naming? Below is an alternative example of my command attempt:
hey, maybe the issue is you used the wrong param and endpoint. try using ‘document’ instead of ‘upload_item’ and sending to /sendDocument. sometimes extra headers confuse curl. give it a go and see if it works
Based on my experience, the likely issue is in the parameter naming and endpoint choice. I encountered a similar problem where including unnecessary header information interfered with curl’s ability to process file uploads appropriately. I resolved it by removing the explicit Content-Type header and switching the parameter to what the API expects, which appears to be ‘document’. Make sure you are using the correct endpoint (/sendDocument, not /sendFile), and verify that the file path is accurate and accessible. This approach should help resolve the issue.
My experience with the Telegram Bot API has taught me that even small details in the cURL command can lead to issues. I once faced a similar problem where I received an error about a missing file, and it turned out that the specific headers I was setting interfered with cURL’s automatic handling of multipart boundaries. In my case, removing the explicit Content-Type header and ensuring that the form parameter matched what the API expected (using ‘document’ instead of a custom name) resolved the issue. Verifying that the file path is correct also made all the difference.
maybe the issue is with ‘chatid’ - try using ‘chat_id’. also, double-check that the file exists and be wary of extra headers as they might conflict. sometimes small changes like this make all the diffrencc
Recent experience with file uploads to Telegram helped me troubleshoot similar issues. I discovered that setting the Content-Type header manually can disrupt curl’s handling of multipart boundaries. It is best to let curl set the header automatically. In addition, ensuring that the file parameter and endpoint perfectly align with the API documentation is crucial. I also verified that the file is accessible under the provided path. Such oversights may seem minor, but they often result in the file not being recognized. A careful review of these aspects resolved the problem for me.
