ESP RainMaker: Issues with external REST API access & using RainMaker cloud in custom apps

[rupeshk74]

Hi,
I’m using ESP RainMaker with my ESP32 project, and I want to connect to my database hosted on Hostinger using a MySQL + PHP REST API. However, the connection is failing.

1. Does ESP RainMaker restrict or block the use of custom REST APIs, or am I missing some configuration that allows external API calls from my device?

2. Can I use the RainMaker cloud and APIs if I build my own custom mobile app instead of using the official ESP RainMaker app?

If yes, what is the recommended way to integrate my custom app with RainMaker — should I directly use the RainMaker REST APIs, or is there a preferred SDK / authentication flow that Espressif provides for third-party apps?.


Thanks in advance.

Sorry I missed replying to this, but not clear what you mean by the external REST APIs in this context. If it is from the phone app, then you can call any API you want.

You can indeed build your own variant of ESP RainMaker app, either by referring the Swagger API docs, or the native phone app SDKs for iOS and Android or the Hybrid app SDK.
