Oneflow tracks every contract from publish to signature and renewal. FlowMattic posts the moments that matter to Slack: a signed deal to the sales channel, a decline to the manager, a first open to the owner and an expired signing period as a reminder to chase. For sales, legal and account teams who send contracts from Oneflow.

1. TriggerContract Sign2. ActionSend Channel MessageWhen Oneflow fires Contract Sign, FlowMattic runs Send Channel Message in Slack with the data from that event.

Each one uses only triggers and actions the two integrations ship today, plus FlowMattic's own tools. Where the library has a ready-made template, import it instead of building from scratch.
Ready-made templateWhen the last party signs, the sales channel gets the contract name, counterparty and value, so the team knows a deal is closed without opening Oneflow.
Contract SignSend Channel Message
View the template Create Channel names a channel after the customer and Invite User To Channel adds the account manager and delivery lead, so kickoff starts in one place the day the deal closes.

Contract Decline posts to a private managers' channel with the counterparty and contract name, so a lost deal gets a quick conversation rather than a silent entry in Oneflow.

Participant First Visit is the best moment to call. Find User by Email locates the contract owner in Slack and a direct message says who just opened it.

When a contract was not signed in time, the sales channel hears about it and Add Reminder sets a follow-up, so the owner can revive the signing period or close it out.

Participant Delivery Failure posts the participant and contract to the sales ops channel, so someone fixes the email address before the deal stalls for a week.

Contract Lifecycle State New Period fires as a recurring contract enters its next period, so account managers see renewals as they happen and can plan the next review.

At the end, each Oneflow contract that is fully signed posts its name, counterparty and value in your sales channel.
Under Connects in FlowMattic, add the Slack workspace your sales team uses.
Create a workflow with Oneflow and the Contract Sign trigger, then add its webhook URL in Oneflow as the trigger step describes.
Send and sign a test contract in Oneflow so FlowMattic captures the contract fields.
Add Slack Send Channel Message, choose the channel, map the contract fields into the text, test it and switch the workflow on.

Fields mapped from the earlier steps (a typical setup)

| Contract value | Message: value |
| Owner | Message: owner |
| Signed date | Message: signed |
A trigger starts a workflow. An action is something FlowMattic does in the app as a step.
Oneflow and Slack connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.
Opens go to the owner, declines to managers and signatures to the team, so each contract moment gets the reaction it needs.
Values and counterparty names pass through your own WordPress site on the way to Slack, not through another company's automation account.
Runs are unlimited on every FlowMattic plan, so a quarter-end rush of contracts costs the same as a quiet month.
Create a FlowMattic workflow with the Oneflow Contract Sign trigger, add its webhook URL in Oneflow, sign a test contract, then add Slack Send Channel Message with the contract name, counterparty and value mapped.
Yes. Use Participant First Visit, then Find User by Email with the owner's email and Send Direct Message. It needs the same email in Oneflow and Slack.
Yes. After Contract Sign, Create Channel names a channel after the customer and Invite User To Channel adds the people who will run the account.
Most teams start with Contract Sign, Contract Decline, Participant First Visit and Contract Signing Period Expire. Lifecycle events such as new periods and terminations suit account management channels.
Only if you build a workflow for it. Contract Content Update and Contract Signature Reset fire for those changes, and you choose whether they post.
