A workflow copies posts from one account (the source) to the accounts you choose (the destinations). You post once on the source, and PostOnce publishes a copy everywhere else. You can also write a post inside PostOnce and send it to several accounts at once with Create Post.

Set it up

1

Connect your accounts

Open Accounts and connect the account you already post on, plus at least one account to copy to. Each platform asks you to approve access on its own login screen. See Connect your accounts for each platform’s requirements.
2

Create a workflow

Click New workflow. Under Post from, choose the platform and the source account. Under Publish or back up to, choose one or more destinations. Click Continue.
3

Choose which posts to copy

Keep New posts going forward ticked to copy what you post from now on. Tick Existing posts as well to repost older posts on a schedule. Review the summary and click Create workflow.
4

Post on the source account

Publish a new post on the source platform the way you normally do. PostOnce picks it up on its next check and publishes it to your destinations.
5

Check the result

Open the workflow. The post appears with a status for each destination. When it shows Published, open the post on the destination platform to confirm it looks right.

Creating a workflow that copies new X posts to a LinkedIn Page

Start with one source and one destination you can check easily. Add more destinations once the first copy looks the way you want.

How long until the copy appears

PostOnce checks each source account on a schedule. Your post is picked up on the next check, then published once the media finishes processing. To check right away, open the workflow and click Check now. Long videos take longer to process before they publish.

The free trial

Try PostOnce free for 7 days. No card is needed. The 7 days start when you activate your first workflow, at the last step of setup (Activate & start trial). During the trial you can connect up to 5 accounts, create up to 3 workflows and publish up to 10 posts. When the trial ends or you use the 10 posts, publishing pauses. Your accounts, workflows and queued posts are kept. Choose a plan to resume. See Plans and billing.
