webhook creation errors

No the domain name is not that. The api domain name is https://ctmapi.tfpest.com/ring/hook . I am the developer that posted the original question, but i was longed in under a different account. That is the API endpoint for this.

Did you try and send it a post request with a Validation-Token header? Because otherwise it will not respond.

WHAT!! wow that is the problem?! I am so glad that you finally raised the issue to the engineering team!! Is there any way that this solution can be included into the documentation, because in terms of Node.js applications, it is pretty common that people use Lets Encrypt for their SSL Certs because of how easy it is to setup.. Or perhaps even better would be to include a list of trusted SSL certificates that the Java programs that ringcentral uses would accept out of the box. This list would be extremely beneficial in any case. Is there any way that is something that you could provide?

I am extremely greatful for that response! It feel good to know that i helped in some way! By any chance could you tell me if Entrust is on that list of CAs that are accepted? Just looking into purchasing an SSL cert now so i can get this application rolled out to my teams. Yeah it would great if LetsEncrypt were an accept CA, because of the fact that they are Free and Extremely easy to use.. Thanks so much!

UPDATE:

I have changed the SSL certificate after paying nearly 300 dollars to get this certificate. I have validated that in fact the certificate has been installed correctly. I have tested to see if it works and I laughed so hard out of pure frustration when I saw the response. I will let the response speak for itself.

{ apiResponse:
   { _externals: { localStorage: [Object] },
     _request:
      { method: 'POST',
        redirect: 'follow',
        headers: [Object],
        url: 'https://platform.ringcentral.com/restapi/v1.0/subscription',
        follow: 20,
        compress: true,
        counter: 0,
        body: '{"eventFilters":["/restapi/v1.0/account/~/extension/~/presence"],"deliveryMode":{"transportType":"WebHook","address":"https://ctmapi.tfpest.com/ring/hook"}}',
        bodyUsed: false,
        size: 0,
        timeout: 0,
        _raw: [],
        _abort: false,
        protocol: 'https:',
        hostname: 'platform.ringcentral.com',
        port: null,
        path: '/restapi/v1.0/subscription',

        originalBody: '{"eventFilters":["/restapi/v1.0/account/~/extension/~/presence"],"deliveryMode":{"transportType":"WebHook","address":"https://ctmapi.tfpest.com/ring/hook"}}' },
     _response:
      { url: 'https://platform.ringcentral.com/restapi/v1.0/subscription',
        status: 400,
        statusText: 'Bad Request',
        headers: [Object],
        ok: false,

        bodyUsed: true,
        size: 0,
        timeout: 0,
        _raw: [Array],
        _abort: false,
        _bytes: 132 },
     _text: '{"errorCode":"SUB-521","message":"WebHook is not reachable","errors":[{"errorCode":"SUB-521","message":"WebHook is not reachable"}]}',
     _json:
      { errorCode: 'SUB-521',
        message: 'WebHook is not reachable',
        errors: [Array] },
     _multipart: [] },
  originalMessage: 'Response has unsuccessful status' }

Your solution did nothing... here is the exact code that I am using to send the request to your server.

let reqBody = {   eventFilters: ['/restapi/v1.0/account/~/extension/~/presence'],   deliveryMode: {    transportType: "WebHook",    address: "https://ctmapi.tfpest.com/ring/hook"   }  }; platform.send({   method: "POST",   url: "https://platform.ringcentral.com/restapi/v1.0/subscription",   body: reqBody  }).then(function (response) {   res.send(response);  }).catch(function (e) {   res.send(e); }); 

Here is an exact copy of the API endpoint https://ctmapi.tfpest.com/ring/hook

router.post("/ring/hook", (req, res) => {     console.log("This is inside of the webhook creation place");     // this console log never gets reached...     let header = 'Validation-Token';     if (req.get(header)) {         res.header(header, req.get(header));         res.send({ test: req.get(header) });     } else {         res.send({ test: req.get(header) })     } }); 

I am using an NGINX proxy server. to access the express node application.

If you send a postman request to https://ctmapi.tfpest.com/ring/hook with a Validation-Token header of 1234567, it returns this list of headers, :

This is everything that I can possibly think of that might need. I cannot think of anything else that you could possibly use for diagnosing the problem.

I am so tired of working on this and I am near the breaking point. I have cost our company SO much money so far because something wrong with this system.
