CONNECTOR OVERVIEW

Overview

Cyclr connects your SaaS product to Slack’s Web API and Events API so you can build customer-facing automations without deep platform knowledge. Map Slack actions into low-code flows, manage per-tenant OAuth installs and expose approved operations as MCP tools. Publish integrations in your embedded marketplace and let customers configure them inside your app.

ORCHESTRATION

How Slack works with Cyclr

Cyclr sits between your SaaS product and Slack to handle authentication, govern access and orchestrate every API call per customer, at scale.

1
Your SaaS product
Your app requests an action for a specific customer.
2
Cyclr orchestration
Cyclr authenticates, applies policies and routes the request.
3
Slack
Slack processes the request and returns a response to your app.

Pagination and rate limits

Pagination

Most list endpoints use cursor-based pagination with next_cursor returned in responses; check each method’s docs for details.

Rate limits

Slack applies tiered, per-method rate limits. Each method’s reference shows limits and retry guidance; implement backoff on 429 responses.

IMPLEMENTATION

Authentication at a glance

Slack uses OAuth v2 to install apps and issue bot or user access tokens; Cyclr handles the OAuth exchange and per-tenant token storage for workspace installs.

Authentication method: OAuth 2.0 (Slack OAuth v2) with bot and user tokens
Credential required: Client ID, Client Secret, OAuth redirect URI and requested scopes per installation.

Before you begin:

Admin consent or elevated scopes may be required for workspace installations.

COMMON QUESTIONS

Frequently asked questions

Cyclr uses Slack’s OAuth v2 install flow to obtain bot or user tokens per workspace and securely stores tokens per tenant.

Yes. Cyclr maps Slack Web API methods such as chat.postMessage and conversations.create into actions you can use in flows.

Treat Slack rate limits as per-method and per-feature. Implement retry with backoff and central throttling to avoid hitting 429s.

Yes. Cyclr lets you expose selected, governed Slack actions as MCP tools so customers can run approved automations inside your product.
