596 "Service Not Found" error against xmlrpc api request

Hi All,

Trying to use the infusionsoft API to get contact details, I always get this error in response at least for the last couple of days:

Response Code = 596
Error message: <h1>596 Service Not Found</h1>

The API URL that I have tried as per the documentation is of the format:

replacing abc with actual token.

The request payload data format is for “ContactService.load” method.

This request is being made through Google apps script (actually I have accessed many API’s like Contstant Contact, SendGrid etc. via apps script to fetch data).

Can anyone guide me what I am doing wrong missing here…


If you’re saying that the endpoint that you specified in your post has been functioning to load contacts from up until “…the last couple of days:” I don’t see how that’s possible as the end point you specify is not the api endpoint. The actual api endpoint is:


In fact, I don’t think that endpoint is used for anything at all.

Thank you @John_Borelli for clariying about the end point.

May be I was confused with the documentation saying: _**All requests except authentication requests made to the Infusionsoft XML-RPC API will be an HTTP POST to https://api.infusionsoft.com/crm/xmlrpc/v1?access_token=123abc**_

So, where should the access token and api key be specified while sending POST requests?

a) Token: in the standard header like 'Authorization' Bearer…?
b) I see a field available in the request body for specifying privateKey. The documentation says it is the API key. Place the API key there inside
<value><string>privateKey</string></value> ?

Please bear with my pretty naive queries as it seems I am not that much experienced in accessing API’s despite having done it for at least five different vendor API’s.

access_token=[your token here] as a URL parameter and then send the remainder request in the body being certain to include the correct content-type header value (eg application/xml)

Thanks @John_Borelli,

But that is exactly what I am doing baseURL + ?access_token=MyToken…
sample code:

//INF_TOKEN is the access token created from I/O Docs page.
//payload data format is copied from the documentation for retrieving a contact detail
//inside that data there is a field for 'privateKey' which is replaced with the API Key.

var url = "https://api.infusionsoft.com/api/xmlrpc/v1?access_token=" + INF_TOKEN;

var params = {
"method": "post",
"contentType" : "application/xml",
"payload" : payload,
"muteHttpExceptions": true
var resp = UrlFetchApp.fetch(url, params);

well, if what you posted here is what you’re trying to use then the url is still wrong.

@John_Borelli Would you mind sharing a sample correct url usage for retrieving a contact based on its email address? It would be much appreciated, thanks.

This is my first usage of xml-rpc. Normally, the API’s like Trello, Constant Contact etc. have parameters appended to the url along with key and the header is included in params object with Authorization Bearer = token combination.

method name: ContactService.findByEmail

Exactly the same url I shared before. Here, I’ll post the one you keep using and the one I posted:

https://api.infusionsoft.com/api/xmlrpc/v1 (you’re using this)
https://api.infusionsoft.com/crm/xmlrpc/v1 (this has to be with crm instead of api)

see the difference now? Next time I would just copy/paste what someone posts as a correction. You can’t correct your own work with your own eyes sometimes.

Thanks @John_Borelli !

Yes, my mistake, I overlooked it in your first message.
It proves the point that testing team can find those errors which the developers can’t.

At least, I get rid of the “service not found” issue, though it is now saying “unauthorized”, most probably token expired set or something else…

Yes, that would be expected with token expired. Just repeat the process to get a new initial token and you should be good.

Finally, with the new token generated, it started responding perfectly fine.
Thanks again, @John_Borelli

By the way, I am surprised as to:

  1. Why their I/O Docs page for live testing with API shows the url that I was using earlier (and you corrected me on that).
  2. Why they have two type of keys: one coming from web account; another from developer portal. Is there a proper one-shot way to tell my clients to get a specific key to work with the API.


So I don’t see any endpoints on the i/o docs page so not sure where you got it from? There aren’t two keys but rather a client id and secret pair (the same as a public and private key I suppose) which allows you to get an auth token. That token allows you to request an access token which is what you would put into the apiKey field.
