Authentication
Before you can access the PredictHQ API and all its magic, you need to prove you are who you say you are. The PredictHQ API uses the OAuth 2.0 standard for authentication.
After you sign up to the API and create an API client with the Control Center, all you need to do is to request an Access Token that will grant your API Client access to the various tools and resources available via the PredictHQ API.
All requests to the OAuth 2.0 endpoint must be given your credentials in the form of Basic authentication. To comply with the HTTP requirements, your Client ID and Secret should be encoded in base 64.
This can easily be done via this command line:
echo -n "$CLIENT_ID:$CLIENT_SECRET" | base64 -w 1000
then by adding a header to your HTTP requests:
Authorization: Basic base64($CLIENT_ID:$CLIENT_SECRET)
URL
https://auth.predicthq.com/token
Because it is based on a standard, the URL to the OAuth2.0 endpoint does not require a version number.
Requesting an Access Token
When requesting an Access Token, use the client_credentials
grant type, then request the scope or scopes you wish to have access to. These scopes can be any or all of the following, separated by a space:
Scope | Description |
---|---|
account | Grants access to the account endpoint. |
events | Grants access to the events endpoint. |
places | Grants access to the places endpoint. |
broadcasts | Grants access to the broadcasts endpoint. |
Access Token Lifetime
Please note that Access Tokens requested via the client_credentials
grant type never expire.
Action
POST /token/
Example
curl -X POST https://auth.predicthq.com/token \
-u "$CLIENT_ID:$CLIENT_SECRET" \
-d "grant_type=client_credentials" \
-d "scope=account events places"
HTTP/1.1 200 OK
Content-Type: application/json
Cache-Control: no-store

{
"access_token": "$ACCESS_TOKEN",
"token_type": "Bearer",
"scope": "account events places"
}
Accessing Protected Resources
Before you can harness the full power of PredictHQ's event intelligence, you need to authenticate your requests using your Access Token.
Once again, to make it easy for you, PredictHQ follows the standard as outlined in the OAuth 2.0 Bearer Token reference.
