Real-Time Audience API endpoint gives invalid format exception

[Andrey]

I’m trying to submit a membership update to real-time audience API endpoint as described in https://dev.twitter.com/ads/audiences/ta-realtime-integration-guide

and always receive this error message “The JSON string format is invalid”, regardless the data sent.

The twurl command used:

twurl -X POST -H “https://ads-api.twitter.com” /1/tailored_audience_memberships --file “group_membership.txt”

The contents of the group_membership.txt file:

[
{
“operation_type”:“Update”,
“params”:{
“membership_type”: “LIST_MEMBERSHIP”,
“advertiser_account_id”:“realID”,
“user_identifier”:“D99E433E9ADA02FB15085BC1DC29EDAA1962C926F187819AA0BBA01E5F1AE54A”,
“user_identifier_type”:“TWITTER_ID”,
“audience_names”:“Membership test”,
“effective_at”:“2016-12-21T00:00:00Z”,
“expires_at”:“2016-12-22T00:00:00Z”
}
}
]

Tried it with --file-field “data”, but no luck.

Please advise how to fix it.

Hey @Andrey

Have you tried using the Content-Type: application/json header when calling this endpoint, as mentioned here ?

Let us know if you’re still seeing issues after using the header.

Thanks!

Hi!

I tried this:

twurl -X POST -H “https://ads-api.twitter.com” /1/tailored_audience_memberships -A “Content-Type: application/json” --file “group_membership.txt”

but still get the same error:

{“errors”:[{“code”:“INVALID”,“message”:“The JSON string format is invalid”}],“operation_errors”:[],“request”:[]}

Hey @Andrey

Thank you for bringing this up! It looks like this may be an issue with twurl itself and the way it’s reading the file. I was able to send the same JSON data, to the tailored_audience_memeberships endpoint, like so:

twurl_ads -t  -X POST --header 'Content-Type: application/json'  --data '[{"operation_type":"Update","params":{"membership_type": "LIST_MEMBERSHIP","advertiser_account_id":"realID","user_identifier":"D99E433E9ADA02FB15085BC1DC29EDAA1962C926F187819AA0BBA01E5F1AE54A","user_identifier_type":"TWITTER_ID","audience_names":"Membership test","effective_at":"2016-12-21T00:00:00Z","expires_at":"2016-12-22T00:00:00Z"}}]' "/1/tailored_audience_memberships" | jq .

{
  "data_type": "tailored_audience_membership",
  "data": [
    {
      "success_count": 1
    }
  ],
  "request": [
    {
      "total_count": 1
    }
  ]
}

Can you confirm if this works for you?

Thanks!

[Andrey]

Yes, passing JSON to a command line works.

Thanks!

Awesome! Please consider marking this thread as resolved!

I’m getting the same issue. Trying to use Python requests oauthlib. I’ve poured over the documentation and can’t find anything. I’ve tried hashing with uppercase

Also, the documented ‘https://ads-api.twitter.com/2/tailored_audience_memberships’ endpoint doesn’t respond.

raw='[{"operation_type":"Update","params":{"membership_type":"LIST_MEMBERSHIP","user_identifier_type":"HANDLE","user_identifier":"b05cfd1f12d82e6cdc18457b6373ba01713b62f02677d3cc49943e735eae7d57","advertiser_account_id":"myid","audience_names":"test"}}]'

res = requests.post('https://ads-api.twitter.com/1/tailored_audience_memberships', headers={'Content-Type': 'application/json'}, auth=OAuth1(...), json=raw)

Any suggestions what I might be doing wrong?

Hey @chet

Thank you for bringing this to our attention. This is currently an issue on our end and we’re actively working towards a resolution. In the meantime, as a potential workaround I would recommend using the same endpoint on v1, i.e.,

/1/tailored_audience_memberships instead of /2/tailored_audience_memberships. We’ll be sure to make an update once we know more.

Thanks!

@imit8me thank you that makes sense–however I’m still getting the “JSON string format is invalid” from the 1.0 endpoint as I documented.

In your experience is there a common point of confusion with the documentation? As you can see from my code sample I’m posting with the content type added as suggested and getting the same issue.

[chet]

Actually I think I got it. Thanks for the help, and I’ll swap to the 2.0 endpoint when it’s ready.

Hey @chet

Great to hear you were able to resolve the problem. Can you post your solution here in case other folks have the same issue?

Thanks!

The data/json parameters in the requests library were confusing me I think since sometimes it tries to form-encode. Best to let it handle the json serialization. This works for me:

post_data=[{"operation_type":"Update","params":{"membership_type":"LIST_MEMBERSHIP","user_identifier_type":"HANDLE","user_identifier":"b05cfd1f12d82e6cdc18457b6373ba01713b62f02677d3cc49943e735eae7d57","advertiser_account_id":"myid","audience_names":"test"}}]

res = requests.post('https://ads-api.twitter.com/1/tailored_audience_memberships', headers={'Content-Type': 'application/json'}, auth=OAuth1(...), json=post_data)
