Setup

Connect it in a few steps.

Set up with Zapier

1
Set the trigger. Create a Zap with Slack as the trigger app and "New message" as the event. Connect your account.
2
Add the API action. Add APIVerve as the action, select the World Time API, and map your trigger data to the request.
3
Send it back. Add a second Slack action for "Send message" and map the returned fields (like search) into it.
4
Test & turn on. Test the Zap with real data to confirm the mapping, then turn it on.

Set up with Make

1
Add the trigger. Create a scenario and add a Slack module set to "New message". Authenticate your account.
2
Call the API. Add an HTTP module pointing at api.apiverve.com/v1/worldtime with your x-api-key header. Pass the trigger's data as the input.
3
Parse & map. Add a JSON module to read the response, then a Slack module for "Send message". Map fields like data.search into place.
4
Activate. Run once to confirm the mapping, then switch the scenario on and set its schedule.

Set up with n8n

1
Add the trigger node. Start a workflow with a Slack trigger node for "New message" and connect your credentials.
2
Add an HTTP Request node. Point it at api.apiverve.com/v1/worldtime using Header Auth (x-api-key). Feed in the trigger data.
3
Map with expressions. Add a Slack node for "Send message" and reference the response with expressions such as {{ $json.data.search }}.
4
Execute & activate. Execute manually to verify, then activate the workflow for production.

Slack + World Time API FAQ

Can I send rich formatted messages with API data to Slack?

Yes. Slack supports Block Kit for rich message formatting. Automation platforms let you construct messages with headers, bullet points, buttons, and formatted data from API responses.

How do I avoid spamming a Slack channel with too many API notifications?

Use filters in your automation to only send important alerts. You can also batch notifications using scheduled digests instead of real-time alerts for non-urgent data.

Can I trigger API calls from Slack messages?

Yes. Set up Slack as a trigger for new messages containing specific keywords. Parse the message content and use it as input for your API call.
