Apify Datasource Pulse n8n Workflow: API Key & Quota Checks + Gmail Alerts

Automatically check your Apify + vendor API keys & quotas—then alert you by Gmail

This n8n workflow runs every morning to validate your Apify Datasource Pulse credentials and quota status, and immediately sends a Gmail alert whenever any check is not healthy—so you can prevent outages before they impact your SaaS or automations.

What this workflow does

• Scheduled daily verification: Triggers every day at 8:00 AM using an n8n Schedule Trigger.
• Runs Datasource Pulse on Apify: Starts the Datasource Pulse actor on Apify with a JSON list of credential and quota checks for vendors (e.g., OpenAI, SerpAPI, and Apify).
• Filters unhealthy results: Evaluates each returned check result and keeps only items whose state is not “healthy”.
• Sends Gmail alerts per issue: For each unhealthy result, sends a Gmail email that includes the message, connector details, state, failure class, and check timestamp.

Setup & customization

• Install the Apify community node and connect your Apify account credentials in n8n.
• In the Datasource Pulse input JSON, replace placeholder API keys/tokens and adjust values like quotaSoftCap and quotaWarningPct to match your limits.
• Connect Gmail in n8n and set the recipient address in the email node (optionally adjust the schedule time).

Use cases

• SaaS operators monitoring vendor quotas to avoid hitting rate limits or hard caps.
• Automation engineers validating that third-party API keys remain usable and aren’t nearing warning thresholds.
• Teams managing multiple integrations (OpenAI, SerpAPI, Apify, etc.) and needing proactive daily alerts.

Technical details

• Nodes/stack: Schedule Trigger, Apify (via @apify/n8n-nodes-apify), if, Gmail, Sticky Note.
• Actor cost: Apify charges $0.02 per key per run.
• Extensibility: The workflow includes pre-wired checks for 35+ vendors, and you can extend to other authenticated endpoints as supported by the actor fields.
