Overview

Connect Heymarket SMS with Flows360

Heymarket is a business texting platform that gives you the power to engage with people using shared inboxes.

Use the Heymarket SMS connector to include its declared actions and events in Flows360 workflows without duplicating the integration logic inside each consuming system. This pinned connector version currently exposes 5 actions and 2 triggers.

Available actions

  • Create or Update Contact
  • Send Custom Message
  • Send Template Message
  • Update List
  • Custom API Call

Available triggers

  • Conversation Started
  • New or Updated Contact

The capability list above is generated from the exact reviewed connector package so the public description stays aligned with the version Flows360 operates.

Setup

Setup

  1. Add the Heymarket SMS connector to the workflow in the target Flows360 Studio instance.
  2. Create or select the tenant-specific connection required by the connector. Connection secrets remain in the Studio connection boundary and are not copied into CDK documentation.
  3. Provide the connection fields declared by the pinned package:
  • No provider credential fields are declared by the pinned package.
  1. Select the required action or trigger and complete its declared input fields. Required and optional inputs are defined by the exact package schema.
  2. Test the workflow in the appropriate environment before enabling production scheduling or event delivery.

Limitations

Limitations and operational notes

  • This content describes @activepieces/piece-heymarket-sms@0.1.0; provider behaviour can change independently and should be revalidated when the provider or connector version changes.
  • Only the 5 actions and 2 triggers declared by this pinned package are represented here.
  • Tenant credentials and connection values are not stored in the public connector record.
  • Provider-side permissions, account entitlements, quotas and rate limits remain subject to the connected provider account and are not inferred when the package does not declare them.
  • Deterministic execution evidence is recorded for the pinned artifact, including 1 exercised action entrypoint and 0 exercised trigger entrypoints.

Troubleshooting

Why canu2019t the connector authenticate?

Check the tenant connection in Studio and confirm every required Heymarket SMS connection field is present. Re-authorise OAuth-based connections if the provider token or consent has expired. Do not place credential values in CDK content or logs.

Why is an action or trigger unavailable?

Confirm that the workflow is using @activepieces/piece-heymarket-sms@0.1.0 and compare the requested capability with the declared action and trigger list for this version. A capability that is not declared by the pinned package should not be presented as supported.

What should I check after a provider-side change?

Revalidate authentication, required fields, action/trigger behaviour and provider documentation before publishing refreshed connector content or moving a new package version into production.
