What Marsial does with LinkedIn

Marsial publishes and schedules content on your own LinkedIn accounts, always with your permission through OAuth, and shows you their statistics. It does not automate interactions (likes, follows or bulk messages) and does not read data from other people's accounts. You can disconnect the account at any time.

How it works

From zero to LinkedIn in minutes

1
Connect LinkedIn
You or your clients connect the account with OAuth from a screen with your brand.
2
Send a request
POST /v1/posts with the content. We adapt it to the LinkedIn format.
3
Receive the webhooks
Posts, replies, messages and metrics arrive at your endpoint in the same format.
