Your URL is not correct–the `image file from device` cannot be used with a URL. ---

Can you link to the documentation for connecting to this API? I can tell you already that there are some current known issues using multipart/form-data as the body type. ---

What is the green response block showing? If you are getting a successful call but the output is not correct, there is an issue with parsing the JSON. I would suggest this tutorial [API JSON Tutorial (Video)](https://community.thunkable.com/t/api-json-tutorial-video/1140575). Let’s get the response first and we can work easier toward figuring out how to drill into the data needed. ---

Hello @aravanagababu595owj3 @tomj20373drj9gy I have merged the community posts since they are talking about the same topic. You can find more information on how to send an image through an API on these community posts: [WEB API Firebase Storage It does not upload the file to the server - Questions about Thunkable / Web API’s - Community](https://community.thunkable.com/t/web-api-firebase-storage-it-does-not-upload-the-file-to-the-server/2369895) [WhisperAPI not working - Questions about Thunkable / Web API’s - Community](https://community.thunkable.com/t/whisperapi-not-working/2656439) ---

Actually I have a dought that thunkable can directly send images to server or not through api where my api only accepts image format. For clarification I have send image and backend responding, and sending message to thunkable but output in thunkable coming as load failed… ![17236066527378661371391061884640](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/2/c/2cb9777310ba5b8fabb8ae45961303fa972b2da5.jpeg) ---

Hello @tomj20373drj9gy Thank you for sharing more information. It is possible to send an image via Thunkable. The way the image is sent is causing the issue. Have you tried to send it as a base64 or as a URL? If these formats don’t work for you, you could use a web viewer instead of the Web API component to make the API call. ---

Hi @aravanagababu595owj3 For the API body, you will need to create a JSON using the “generate json from object” and “create object” blocks ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/e/1/e12fb89cced8dec37f34198da2ac32f916aa63fa.png) ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/c/2/c269fda9056abb49b7338340c084124648be26e5.png) ---

Hello @aravanagababu595owj3 Based on your last screenshot, you have a “get” API call, have you tried to make it “post”? Also, on the API body, the field name needs to be set based on your API. Hello @ramlord704ak26pw , welcome to Thunkable! 🎉 Do you use the same API URL? Does it accept a JSON as an input?
