Start here: [Curl - HTML/CSS to Image](https://docs.htmlcsstoimage.com/example-code/curl/) I’m trying to see if I can get it working, too. ---

The difficulty arises from the fact that URL should not exceed 64K bytes and the Base64 you are creating is much longer this leads to the URL to fail. ---

I’ll have a look at this tomorrow, and tell you the result. It’s getting late. ---

@muneer Yes, you’re right. @codeswept I’ve never gotten a POST command to work in Thunkable but I know it’s possible. Here’s the code I’m trying: ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/b/9/b9088d6c31d8c8ae3f71e92d1ac1a5c090fd089a.png) But it requires authentication that I haven’t gotten quite right in Thunkable. I also tried this in Postman using a `curl` command but the API server returned a `414 Request-URI Too Large ` error so **I think I have to give up on this method.** ---

It looks like both of these APIs accept Base64 as input. Have you tried either? > **[Detect text in images  |  Cloud Vision API  |  Google Cloud](https://cloud.google.com/vision/docs/ocr#vision_text_detection-drest)** [https://ocr.space/ocrapi](https://ocr.space/ocrapi) ---

Interesting! Last night I had a dream of a Curl Command chasing after me with a knife😖 I hoped that the second link offered GET calls but ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/d/3/d30455477fa0cba5cc301ac598db36959b7f22c1.png) ---

I think you need to put `generate JSON from object` before `image of Canvas1` to have it as Base64 sting of the image ---

Let me try that. ---

After ‘set qp’ I don’t get anything in my input. ---

Should I put the Image of Canvas1 block in the header or as a Query Parameter? ---

I have to check the documents of the API itself. I took a quick look on one of the examples in `Postman` and the only parameter in the header in the API key. However, from what I know, both header and query part should not be long and you want a Base64 that is over 100K in size so you need to consider having it in the `body` part of the API. ---

If I put it in the body part, then it doesn’t accept the CREATE OBJECT block. Do I directly use the ‘generate json’ block? ---

for the `body` part of the API. all engines expect text so even if you need to code it as an object in thunkable then you need to proceed that with `generage JSON from object` ---

I have done that. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/8/4/84db2b18901c36e79d09f1a920a6928c9097421f.png) ---

No. It should be `Base64image` parameter of the body. You will need to use the create object to do that.
