getIntegrationsTelegramLinkCallback method
Complete the Telegram account link
The final leg: it binds the verified Telegram user to the Hanzo account that just signed in, and answers a short confirmation page telling them to return to Telegram. The Hanzo credential is sealed into the connected org's KMS namespace. This is one leg of a three-leg flow, and the legs are not interchangeable: a browser is expected to arrive here only from the leg before it. The link URL's state proves the prompt was server-minted and carries the CHAT it started from — it is provenance only, and it never decides which account gets linked. The account identity always comes from the platform's own verified sign-in and a host-bound cookie, so forwarding a link to someone else cannot bind their account, and a session lifted into another browser is refused rather than completed. Each link is single-use, and a deployment without linking configured answers 503.
Implementation
Future<void> getIntegrationsTelegramLinkCallback() async {
final response = await getIntegrationsTelegramLinkCallbackWithHttpInfo();
if (response.statusCode >= HttpStatus.badRequest) {
throw ApiException(response.statusCode, await _decodeBodyBytes(response));
}
}
