I decided to do my own Iota Client Library on Qt, until the C one from the foundation is out (because Rust is killing me).
I have check HTTP REST API documentation. I have implemented a minimal message( only with the "payload" key) and is working. But when i try to send many big payloads(less than 31k) on the mainnet i get Gateway timeout error (I think is error 503).
I am trying to send a full indexation message now. So, my question is how i can get the missing fields on the post request.
"parentMessageIds:" ?(I will try with /api/v1/tips)
More importantly how to do the POW on the device(I think is related with the nonce parameter). I do not find any literature about this. And if you know about why i am getting the Gateway timeout error on the mainnet and not on the devnet load balanced endpoints.
If you can give me any reference will be appreciated.
