I am using above code to create carousel (Image) template

1. Use upload session like this https://graph.facebook.com/v20.0/{{APP_ID}}/uploads?file_name=8-Titanium Grey.png&file_length=97700&file_type=image/png
2. From the response, use the ID to upload like this https://graph.facebook.com/v20.0/upload:{{id}}
3. From the response, you will get header_handle

As per suggested steps, I am able to perform step 1 and 2 but not getting desire details after performing step 3 and getting an error i.e.,

{"debug_info":{"retriable":false,"type":"NotAuthorizedError","message":"User not authorized to perform this request"}}

And I am using below URL as step 3 i.e.,

https://graph.facebook.com/v20.0/upload:MTphdHRhY2htZW50OjZiNzEzM2VjLTYwOTMtNDc2YS04MmFlLTNmNGE0Zjc1YTE5Nj9maWxlX25hbWU9UHJvZHVjdDEmZmlsZV9sZW5ndGg9OTc3MDAmZmlsZV90eXBlPWltYWdlJTJGanBn?sig=ARYS9qcR6BFOIXCQIsQ

@Purusothaman help me to come out from this issue

Step 1,2,3 is used for getting template approval. If your carousel cards contains image then it must be done. For sending carousel - you have upload image and use the returned image id For ex : curl -X POST 'https://graph.facebook.com/v20.0/<PHONE_NUMBER_ID>/media' \ -H 'Authorization: Bearer <ACCESS_TOKEN>' \ -F 'file=@"2jC60Vdjn/cross-trainers-summer-sale.jpg"' \ -F 'type="image/jpeg"' \ -F 'messaging_product="whatsapp"'

From your JSON : don't use {{1}} like this in JSON, instead you should use parameters field
