Connect

Auth type: OAuth (oauth2). Click Connect and approve access on the provider's page. Appbricx runs the OAuth flow (signed single-use state, PKCE where the provider supports it), stores the tokens encrypted and refreshes them before they expire.

Scopes requested: chat:writechannels:readchannels:manageusers:readreactions:write

OAuth needs an OAuth app: the platform's when the operator configured one, or your own (admin panel, Integrations, Configure). You can also bring your own credentials.

  • In the editor: Backend panel, Integrations tab, then Connect. This connects it for the project.
  • For every project in a workspace: Workspace settings, Integrations.
  • Owners and admins choose which integrations members may connect in the admin panel (Integrations tab), and can attach their own OAuth app there.

Call it from a workflow

Pass the action name and its input. The call resolves with { success, output, error? }; a missing connection resolves with success false and the reason. See ctx.integrations.invoke and ctx.integrations.call.

Native workflow
// .workflow.js (native ctx)
export async function run(ctx) {
  const res = await ctx.integrations.invoke("slack", "send_channel_message", {
    "channel": "<channel>",
    "sendAsBot": true
  });
  if (!res.success) throw new Error(res.error);
  ctx.log.info("Slack answered", { output: res.output });
}
defineWorkflow module
// defineWorkflow module (@app/sdk ctx)
import { defineWorkflow } from "@app/sdk";

export default defineWorkflow({
  id: "slack-send-channel-message",
  name: "Slack: Send Message To A Channel",
  description: "Calls Slack when a row is created.",
  trigger: { type: "entity_event", entity: "tickets", event: "created" },
  async run(ctx, event) {
    const res = await ctx.integrations.call("slack", {
      "action": "send_channel_message",
      "channel": "<channel>",
      "sendAsBot": true
    }) as { success: boolean; error?: string };
    if (!res.success) throw new Error(res.error);
  },
});
From an app (connector proxy)
curl -X POST "$APP_ORIGIN/__appbricx/connector-proxy/slack/send_channel_message" \
  -H "Authorization: Bearer $APP_KEY" \
  -H "content-type: application/json" \
  -d '{"props":{"channel":"<channel>","sendAsBot":true}}'
