Unable to make image beacon work (400 Bad request errors)

[Yonezpt]

I have been trying to load a simple image beacon to test the data collection, but it is always returning a 400 bad request error. I am using the following url for the image beacon created by following the examples in the guides:

https://api.keen.io/3.0/projects/ <my project id> /events/event_collection_test?api_key= <my write key> &data=%7B%22campaign%22%3A%20%22Awesome%20analytics!%22%2C%22subject%22%3A%20%22Hi%22%2C%22text%22%3A%20%22Image%20beacons%20are%20fun.%22%7D

Hi Yonezpt, the data portion of the URL parameter must be Base64 encoded and a JSON string.

You can use the JavaScript btoa method to create the base64 portion, and most other languages have native Base64 encoding functions.

In JavaScript, this likely looks like: btoa(JSON.stringify({ campaign: "Awesome analytics!" }))

Hope that helps!

That did the trick, thanks for the quick response.
