Hi @anuriel - hope to help you with this! Would you mind trying this endpoint in your Identify call? 

(please note it is identical to the endpoint you have already tried except there is a “2” after “api”)

Please let me know how this goes for you!

First I’d like to say thanks for the help!

it seems like I’m still getting the missing_event error.

I’m attaching the post request using curl that im running maybe the request will be clearer there…@jmagg any chance you can try running the request with your api key and see what you get?

curl --location --request POST 'https://api2.amplitude.com/identify' \

--header 'Content-Type: application/json' \

--data-raw '{

"api_key": API_KEY,

"identification": i

{

"user_id": "kqlvwyvomsxnaets_170",

"user_properties": {

"company": "kqlvwyvomsxnaets",

"industry": "healthcare",

"numberOfEmployeeRange": "21-50",

"signupTimestamp": "1616678036",

"conversionToPaidTimestamp": "1628003369",

"planId": "enterprise",

"userRole": "owner"

},

"country": "Israel"

}

]

}'

so after talking to one of their sales people that send the question to one of the tech people, I got this information:

“missing_event” gets sent when they are not able to parse the request correctly.

looks like a general error that isn't explained…

the way I got it to work in the end is sending identification as a json stringify instead of the whole json object. which is kinda weird but what ever

so my payload was:

{

"api_key": API_KEY,

"identification": “o{“user_id”:”blablabla”...}]”

}

Hi @anuriel - sorry for the delayed response here! Glad to hear you resolved the issue 

I’m hitting this too, and changing my payload to encase the identifications in a string didn’t help. Working in python, and using this data as a json body in a POST to https://api.amplitude.com/identify.

I’m previously tried:

{
  'api_key': '<my-key>',
  'identification': t{
    'user_id': 'my_id',
    'user_properties': {'email': 'me@mydomain.com'}
  }]
}

After reading the above, I tried:

{
  'api_key': '<my-key>',
  'identification': 'i{"user_id": "my_id", "user_properties": {"email": "me@mydomain.com"}}]'
}

I’m still getting the very uninformative “missing_event” 400 error.

Meanwhile, a direct curl call that follows the style given on https://developers.amplitude.com/docs/identify-api, with the two --data arguments (--data api_key=<my-key> and --data identification=a{...}]), works. (Returns 200, effectively changes my email.)

(Is there a difference between the two --data arguments and one JSON dictionary?)

Hi @apollograce ,

I have an answer for the above on this thread. Would you be so kind as to see if it helps? Thank you.

Kind Regards,

Denis

Hi, @anuriel & @apollograce!  I wanted to close the loop here. Were you able to resolve the issue? I’m looping in platform specialist @ning.chang, who can take a closer look, if needed. Leave us a comment if you need us!

Hi,

Seems like this API is broken. 

Could someone let me know how to make this Identity API work please?

I tried the sending a JSON payload using https://api2.amplitude.com/identify
JSON Payload:

{
    "api_key": "MY API KEY",
    "identification": "t{\"user_id\":\"b2d0dc3e-7ec4-48ad-bdbf-30723d461067\", \"user_properties\":{\"$set\": {\"province\":\"ON\"}}}]"
}

I also tried
 

{
    "api_key": "MY API KEY",
    "identification": "n{\"user_id\":\"b2d0dc3e-7ec4-48ad-bdbf-30723d461067\", \"user_properties\":{\"province\":\"ON\"}}]"
}

Each time I get a HTTP 400 missing_event.

Could the API be improved so that we get a detailed error message also.

​​​​​​​Thanks

Hi @Stephane ,

That looks like an issue with the way the API call is being done as I am able to use the API myself. Can you create a community post and myself or one of my teammates will pick it up as soon as we can? Thank you!

I would also recommend the URL endpoint https://api2.amplitude.com/identify 

Are you passing the parameters in form-data or as query params? If you can create the community post, we will help you there, thank you!

Hi @Denis Holmes 

I was able to make it work using form-data.  See here my question:

In my first attempt to use the API, I was trying to pass in a JSON body which does not work as per the documentation.

Hi @Stephane ,

I see in the documentation they say to pass it in the body of the request. I see the content type is not specified.  If your request is formData but you’re putting it in the raw window, you would need to include the Content-Type header so your API knows how the data is formatted. This is not recommended though. 

I would use the form-data as the content-type is automatically set for you. Content-Type: application/x-www-form-urlencoded.
