Additional information

I'm trying to set up the docker container for homeassistant for a land-line number using this readme:
https://github.com/bbernhard/signal-cli-rest-api/blob/master/doc/HOMEASSISTANT.md

Using this line of code:
curl -X POST -H "Content-Type: application/json" --data '{"use_voice": true}' 'http://127.0.0.1:8080/v1/register/+43123456789

I get the reply:
{"error":"Captcha required for verification, use --captcha CAPTCHA\nTo get the token, go to https://signalcaptchas.org/registration/generate.html\nAfter solving the captcha, right-click on the \"Open Signal\" link and copy the link.\n"}

So I go to https://signalcaptchas.org/registration/generate, solve the captcha and get a link like:
signalcaptcha://signal-hcaptcha.5fad9...aEIVfjTLs4E

As descripted in the readme, I then do:
curl -X POST -H "Content-Type: application/json" -d '{"captcha":"signal-hcaptcha.5fad9...aEIVfjTLs4E", "use_voice": true}' 'http://127.0.0.1:8080/v1/register/+43123456789'

But here I only get the reply:
{"error":"Failed to register: StatusCode: 429 (RegistrationRetryException)\n"

I couldn't find any information about this error. The land-line number I use isn't registered for Signal yet (it's mine for over 10 years and I never tried a registration before).

Any idea what might be wrong?

Added:
Since the error is "RegistrationRetryException", I tried to figure out if the number has been registered (somehow):

http://127.0.0.0:8080/v1/receive/+43123456789

results in:

{"error":"User +43123456789 is not registered.\n"}

I found out that when deleting all files in /signal-cli-config/, the error "RegistrationRetryException" vanishes.

Can't check if it fully works because I get a "Rate limit exceeded"-error now. So waiting for that to vanish too...

[Cangoo]

Nope, still get {"error":"Failed to register: StatusCode: 429 (RegistrationRetryException)\n". Any ideas?

Got a bit of the same issue. For captcha you have to use the complete url (including signalcaptcha://), at least that worked for me. Now I'm stuck with the verification. Got the verification number via sms but I get "Verify error: StatusCode: 404" trying to verify it.
I also hit the rate limit now.

[Cangoo]

Hi and thanks for your reply and the hint with the signalcaptcha:// - very helpful.

I now managed to get the call for the verification number by doing this (see https://github.com/AsamK/signal-cli/wiki/Quickstart#set-up-an-account):

curl -X POST -H "Content-Type: application/json" --data '{"use_voice": false, "captcha":"signalcaptcha://signal-hcaptcha.5fad...Rk--Ro"}' 'http://127.0.0.1:8080/v1/register/+43123456789'

WAIT 60 sec

curl -X POST -H "Content-Type: application/json" --data '{"use_voice": true, "captcha":"signalcaptcha://signal-hcaptcha.5fad...YmYTv56fA"}' 'http://127.0.0.1:8080/v1/register/+43123456789'

The link above claims that Failed to register: [429] Rate limit exceeded: 429 (RateLimitException) might be an error if you are not doing this correctly (first use voice=false, then wait, then voice=true).

But now I'm stuck at the same point as you:
curl -X POST -H "Content-Type: application/json" 'http://127.0.0.1:8080/v1/register/+43123456789/verify/123-456'
=> {"error":"Verify error: StatusCode: 404\n"}

Do you now if the format for the code is '123-456' or '123456'? Okay, both didn't work...

[Cangoo]

Uh, oh, eh, although I got the verification-error, I'm now able to send messages. Yay!

[A380Coding]

What did you change to verify?

[Cangoo]

Not sure what did the trick. I tried:

curl -X POST -H "Content-Type: application/json" 'http://127.0.0.1:8080/v1/register/+43123456789/verify/123-456'

and

curl -X POST -H "Content-Type: application/json" 'http://127.0.0.1:8080/v1/register/+43123456789/verify/123456'

several times, I even called: http://127.0.0.1:8080/v1/register/+43123456789/verify/123-456 in the browser, always getting "Verify error: StatusCode: 404". I then out of fun tried to receive messages which suddenly worked.

Added: I tried to receive in browser by calling:
http://127.0.0.1:8080/v1/receive/+43123456789
and got an empty array [ ] back.

Hey, got it working by waiting 60 seconds before setting use_voice to true too. I also removed the hyphen in the registration code in the verify URL.

[Cangoo]

Hello, I just tried it with another landline-number and it worked like charm on the first try using no hyphen in the code to verify the number.

[flocsi]

Does not work for me. Verifying results in "StatusCode: 404"

[bbernhard]

please try with Version 0.80

[flocsi]

Even with V 0.80, I receive "Verify error: StatusCode: 404" after entering the code I received via phone call.

I found that I was getting 429 when I specified use_voice to true initially. It seems that you just set use_voice to false, make a request, then set use_voice to true. And only provide it a captcha after getting an error stating it is required. I also found that on my second attempt after setting use_voice to true, it required another request with the same payload to give me a successful response.

For me, the following worked:

1. use_voice false without captcha
2. use_voice false with captcha
3. use_voice true without captcha ---> 429
4. use_voice true without captcha ---> 201

[flocsi]

I get "StatusCode: 502 (ExternalServiceFailureException)". Perhaps, it is an issue with this particular landline number that has been used earlier.
