Agents create and update leads, assign and remove tags to drive Kartra automations, subscribe contacts to mailing lists, and grant membership site access after a purchase. [Verified](https://flowrunner.ai/integrations/verified "What does verified mean?") · 7 actions · API key · available [Kartra website](https://kartra.com/) · [Platform Documentation](https://documentation.kartra.com/article/api/) · Capability data verified 2026-07-28 1. A course purchase completes in the external storefront 2. Agent verifies the payment actually settled in the payment processor 3. Create Lead adds or refreshes the buyer in Kartra, keyed on email 4. Assign Tag applies the buyer tag that starts the post-purchase sequence 5. Subscribe To List places the buyer on the customer newsletter 6. Access grants the agent cannot tie to a settled payment, a refund in flight, a mismatched email, wait for a person 7. Grant Membership provisions the course access once cleared 8. The operations channel logs the buyer, the payment reference, and the access granted ## What This Integration Enables Kartra bundles the funnel, the email sequences, and the membership site into one machine, and the machine runs on two inputs: what a lead's record says, and which tags it carries. Businesses that sell only through Kartra's own checkout get those inputs for free. Everyone else, selling through Shopify, Stripe, webinars, or a sales team, has a gap between where money changes hands and where access and automation live. FlowRunner agents close that gap, with the one write that gives away the product held behind a human gate. - Create or update leads whenever a form is submitted or an order is placed anywhere in the stack - Tag and segment contacts to drive Kartra automations and email sequences - Subscribe contacts to mailing lists and nurture sequences - Grant membership site access after a verified purchase or approved manual enrollment - Look up a lead's full profile, tags, lists, and memberships, before taking further action Tags in Kartra are automation triggers, and memberships are the product itself. Both writes get the respect they deserve through FlowRunner's [human-in-the-loop](https://flowrunner.ai/concepts/human-in-the-loop) discipline. Email-keyed identity is the quiet advantage here. Because Kartra resolves every lead by email address, FlowRunner flows never juggle foreign IDs between systems: the same address that identifies the customer in Stripe, Shopify, or a form response identifies them in Kartra, and Create Lead's built-in upsert behavior means repeated events converge on one record instead of manufacturing duplicates. Sync logic stays simple, and simple sync logic is the kind that still works a year later. ### Without FlowRunner **Purchases outside Kartra provision by hand**: Buyers from other checkouts wait hours for course access while someone works through the enrollment queue **Tags depend on memory**: Segmentation happens when a human remembers to tag, so sequences fire late or on the wrong people **The lead record is partial**: Kartra sees what happened inside Kartra, and everything from the CRM, store, and forms stays invisible ### With FlowRunner **Access follows payment in minutes**: Verified purchases provision membership access automatically, any hour of any day **Tags fire at the moment of the event**: Every source applies its segment tag on arrival, and Kartra's automations take over from there **The whole stack feeds the lead**: Forms, stores, and payment systems create and update leads continuously, keyed on email ## Use Case Scenarios ### The course purchase that provisions itself A buyer completes checkout in [Shopify](https://flowrunner.ai/integrations/shopify). The agent confirms the order is paid, calls Create Lead with the buyer's details, applies the course tag with Assign Tag, and calls Grant Membership for the matching membership site. The buyer's welcome email from Kartra's own automation arrives with working login access, minutes after payment, at 2 AM on a Sunday if that is when they bought. ### Webinar registrants segmented before the replay goes out Registrations flow in from [Typeform](https://flowrunner.ai/integrations/typeform). The agent creates each registrant with Create Lead, tags them by the interest they selected, and subscribes them to the webinar list with Subscribe To List. After the event, attendance data updates the tags: attended one tag, no-show another. Kartra's sequences then speak to each group differently, and the replay email writes itself into the right inboxes. ### Stripe subscribers who never fall through the crack A new customer appears in [Stripe](https://flowrunner.ai/integrations/stripe). The agent checks Get Lead for an existing record, creates or updates the lead, subscribes them to the customer nurture list, and logs the pairing of Stripe customer ID to Kartra lead in [Google Sheets](https://flowrunner.ai/integrations/google-sheets). When a subscription lapses, Remove Tag pulls the active-customer tag so win-back automation takes over. Revenue state and marketing state finally agree. ## Human-in-Loop Highlight Grant Membership hands out the thing customers pay for. One call, identified by nothing more than an email and a membership name, and a person has full access to the course or community; there is no invoice check built into the API, and access granted wrongly is revenue you will spend support cycles clawing back, if you claw it back at all. So FlowRunner flows bind that call to evidence: the agent grants only when it holds a settled payment reference from the processor, and everything else stops. A chargeback filed minutes after purchase, an enrollment request from an email that matches no payment, a typo'd address that would provision a stranger: each posts to the operations channel as "Grant blocked: no settled payment found for j.smith@example.com against Creator Academy. Approve manually or investigate?" A person decides. The adjacent trap gets the same care: Assign Tag silently creates any tag that does not exist, so agents tag only from a maintained vocabulary, because a misspelled tag does not error, it quietly forks your segmentation. Agent processes routinely Detects exception requiring judgment Clear match Continues automatically Ambiguous Routes to human via email Human decides Agent resumes with decision ## Agent Capabilities 7 actions ### Leads 3 - **Create Lead** Creates a lead with email and optional profile details. Kartra keys leads on email, so an existing address is updated rather than duplicated, making this the safe default write for every source. - **Get Lead** Retrieves a lead's full profile by email: ID, contact fields, tags, subscribed lists, and membership access. The context read before tagging, granting, or updating. - **Update Lead** Updates profile fields on an existing lead by email, changing only the fields supplied. The enrichment write for syncs from the CRM and store. ### Tags 2 - **Assign Tag** Assigns a tag to a lead by email, creating the tag automatically if it does not exist. Tags trigger Kartra automations, so FlowRunner agents assign only from an approved vocabulary. - **Remove Tag** Removes a tag from a lead, reversing the segmentation or automation trigger tied to it. Removing an absent tag is a no-op, which makes it safe in cleanup sweeps. ### Lists 1 - **Subscribe To List** Subscribes a lead to an existing mailing list by name. The opt-in step for newsletters and nurture sequences. ### Memberships 1 - **Grant Membership** Grants a lead access to an existing membership site by name. The operation this page's human gate exists for: it provisions the product itself. ## Frequently Asked Questions ### What can FlowRunner do with Kartra?
