The conversions token can only send leads and sales. To send your audiences, read your spend and create campaigns, each network needs a connection to its marketing API: More networks tab, each card, "Audiences, spend and campaigns".
It is a separate key that each network gives to an app you register. Some review the app first:
- TikTok: create an app in the TikTok API for Business portal with Ads Management, Audience Management, Reporting and Creative Management. TikTok reviews it in 2 to 3 business days. The access token does not expire.
- LinkedIn: request the Advertising API (and Matched Audiences for lists) for your app. LinkedIn reviews it. Tokens last 60 days; with a refresh token they renew by themselves.
- Pinterest: an app with ads read and write access (Standard access is reviewed). Tokens renew with the refresh token.
- Reddit: create a developer app in Reddit Business Manager. Reading spend works straight away; audiences and campaigns need Reddit's approval for Ads API write access (ask your Reddit account team, or apply through Reddit for Business).
- Snapchat: create an OAuth app in Business Manager, Business Details (you need to be an Organization Admin). Tokens last an hour and renew by themselves.
Paste the account id, the access token, and the refresh token, app id and app secret where your app has them. Save and check reads your account name and currency to prove it works. For creating campaigns also add: your LinkedIn company page id, your Pinterest board id, or your Snapchat public profile id.
