Grassrootz runs peer-to-peer fundraising for charity events: walks, rides, challenges and galas. FlowMattic posts the activity to Slack so the events team can cheer people on and act quickly: each donation, each new fundraiser or team, tickets sold, a fitness activity logged. Supporter care staff follow the whole campaign from a few channels.

Grassrootz and Slack workflows you can build
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 template
Post each Grassrootz donation to the fundraising channel
Gifts appear with the amount and the fundraiser they support, so the team can thank donors and share momentum on social media during the event.
When someone creates a fundraising page, supporter care hears about it, so a staff member can send a welcome pack and tips while the fundraiser is keen.
Fundraiser Created→Send Channel Message
Tell the corporate partnerships lead about new teams
Teams are often workplaces taking part together. A direct message to the partnerships lead means each new team gets a call about matched giving or sponsorship.
Team Created→Find User by Email→Send Direct Message
Track event ticket sales in the event channel
Each ticket sold posts to the channel for that event, so the logistics team knows how many people to plan for and when to order shirts and medals.
Ticket Created→Router→Send Channel Message
Celebrate logged fitness activity during a challenge
For distance or step challenges, each fitness activity a participant logs posts to a challenge channel, giving staff stories to share and people to encourage.
Fitness Activity Created→Send Channel Message
Flag cancelled regular gifts for supporter care
When a donation subscription is deleted, a private channel hears about it, so supporter care can thank the donor for their support and ask whether anything went wrong.

Triggers and actions in this pair
A trigger starts a workflow. An action is something FlowMattic does in the app as a step.
Good to know
Grassrootz has separate created, updated and deleted events for most records. Start with the created events, and add updates only where the team needs them, or the channels get noisy.
Some donors give anonymously or hide the amount. Check the captured test donation for those fields and leave them out of public channels.
The fields in the mapping are typical examples; check the captured data for the names your Grassrootz campaigns send.

Why run this pair with FlowMattic
Grassrootz and Slack connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.
Event days are easy to follow
Donations, tickets and activity show up in Slack as they come in, so the whole team sees the event build without refreshing reports.
Fundraisers get support early
New fundraisers and teams reach supporter care and partnerships straight away, when a welcome call makes the most difference.
No per-event cost
FlowMattic runs on your WordPress site with unlimited runs, so a big mass-participation event costs nothing extra to automate.
Common questions
How do I send Grassrootz donations to Slack?
Connect Slack in FlowMattic, start a workflow with the Grassrootz Donation Created trigger and add Send Channel Message. Map the donor, amount and fundraiser, make a test donation and switch the workflow on.
Can each event have its own channel?
Yes. Add a Router after the trigger with one path per event or campaign name. Each path posts to its own channel with Send Channel Message.
Which Grassrootz events are most useful in Slack?
Most teams start with Donation Created, Fundraiser Created, Team Created and Ticket Created. For challenge events, Fitness Activity Created gives the team stories to share.
Can I keep donor details out of shared channels?
Yes. Choose only the fields you want in the message, and use Send Private Channel Message for anything that should be seen by fundraising staff only.
