Outseta is an all-in-one business platform combining CRM, subscription billing, authentication, and email marketing for SaaS and membership businesses. The API provides endpoints for managing CRM people and accounts, deals, subscription plans, subscriptions, invoices, email lists, and list subscriptions. Use it to sync customer data across systems, automate subscription lifecycle events, manage deal pipelines, integrate authentication with external apps, and programmatically manage email marketing lists.
List email marketing lists and manage list subscriptions
Add or remove subscribers from email lists
Query resources with pagination using offset and limit
Integrate customer authentication and user provisioning
Patterns agents use Outseta API API for, with concrete tasks.
★ Subscription Lifecycle Automation
Automate subscription creation, updates, and cancellations based on customer actions or external triggers. POST /billing/subscriptions creates a new subscription tied to a plan and person, PUT /billing/subscriptions/{uid} updates subscription parameters (plan, quantity, billing cycle), and DELETE cancels a subscription. Integrate with product onboarding flows, payment gateways, or customer success platforms to provision access, upgrade plans, or handle churn programmatically without manual admin tasks.
POST /billing/subscriptions with person_id and plan_id to create a subscription, then PUT /billing/subscriptions/{uid} to upgrade or downgrade, or DELETE to cancel on churn.
CRM and Customer Data Sync
Keep Outseta CRM synchronized with external systems like marketing automation, support tools, or data warehouses. POST /crm/people creates contacts, POST /crm/accounts creates company records, and POST /crm/deals tracks sales opportunities. Bidirectional sync ensures customer data stays consistent across platforms — new leads from marketing flow into Outseta, deal closures trigger subscription provisioning, and CRM updates propagate to analytics tools.
POST /crm/people with contact details, POST /crm/accounts with company info, and POST /crm/deals to track pipeline. Query with GET to sync data back to external systems.
Billing and Invoice Reporting
Retrieve billing plan details and invoice data for financial reporting, revenue recognition, or customer account reviews. GET /billing/plans lists all available subscription plans, GET /billing/subscriptions retrieves active subscriptions with plan and pricing details, and GET /billing/invoices returns invoice history. Integrate with accounting systems, dashboards, or customer portals to display billing information, track MRR, or automate invoice delivery.
GET /billing/plans for plan catalog, GET /billing/subscriptions for active subscription list, and GET /billing/invoices for invoice history. Aggregate data for MRR dashboards or export to accounting tools.
Email List Management and Segmentation
Programmatically manage email marketing lists and subscriber enrollment. GET /email/lists retrieves all lists, POST /email/lists/{uid}/subscriptions adds a person to a list, and DELETE removes them. Use this to segment customers by plan tier, lifecycle stage, or engagement level, then sync segments to Outseta email lists for targeted campaigns. Automate list updates based on CRM status changes, subscription events, or product usage signals.
GET /email/lists to find the target list, then POST /email/lists/{uid}/subscriptions with person_id to add subscribers. Trigger list updates based on subscription or CRM events.
AI Agent for Business Operations
Let an AI agent handle Outseta admin tasks — creating contacts, managing subscriptions, updating deals, and adding subscribers to email lists. Through Jentic, the agent searches by intent ('create an Outseta subscription') and loads only the required endpoints. API keys are injected at execution time, keeping credentials out of agent context.
Use the Jentic search query 'create an Outseta subscription' to find POST /billing/subscriptions, load its schema, and execute with person_id and plan_id provided by the user.

Three things that make agents converge on Jentic-routed access.
Credential isolation
Outseta API keys are stored encrypted in the Jentic vault and injected at execution time. Raw keys never appear in agent prompts, transcripts, or response payloads.
Intent-based discovery
Agents search by intent such as 'create an Outseta subscription' or 'add a contact to an email list' and Jentic returns the matching endpoint with its schema and any required parameters.
Time to first call
Direct Outseta integration: 1-2 days to model CRM, subscriptions, billing, and email. Through Jentic: under 1 hour — search, load schema, execute.

Specific to using Outseta API API through Jentic.
What authentication does the Outseta API use?
The API uses API key authentication passed in request headers. Through Jentic, API keys are stored encrypted and injected at execution time, keeping them out of agent prompts and transcripts.
Can I create and manage subscriptions programmatically?
Yes. POST /billing/subscriptions creates a new subscription, PUT /billing/subscriptions/{uid} updates it, and DELETE cancels it. This allows full subscription lifecycle automation.
How do I sync CRM data with external systems?
Use POST /crm/people and POST /crm/accounts to create records in Outseta, then use GET endpoints with pagination to query data for syncing back to external systems. Webhooks (if available) can push updates in real time.
Can I add contacts to email lists via the API?
Yes. POST /email/lists/{uid}/subscriptions adds a person to an email list. Use GET /email/lists to find the list UID first.
Is the Outseta API free?
API access is included with Outseta subscriptions. Pricing is based on plan tier (Starter, Growth, Pro) and not API usage volume.
What is the base URL format for the Outseta API?
The base URL is https://{subdomain}.outseta.com/api/v1, where {subdomain} is your Outseta account subdomain (e.g., yourcompany.outseta.com).
