The news
Plaid said on September 28 that it is partnering with Decagon, a maker of AI customer service software, so that Decagon AI agents can connect to, verify and act on a customer's bank account through Plaid without sending the customer out of the conversation.
The problem the companies are targeting is the handoff. Many common support requests in financial services require the customer to log in to their bank first, Plaid said in a blog post announcing the deal, and making people leave the chat to do that disrupts the exchange and, in many cases, brings it to an end.
Under the partnership, a Decagon agent can prompt a customer, by voice or text, to reconnect their accounts once through Plaid Link, the widget consumers use to link bank accounts to apps. Roger Liang, who works on strategic partnerships at Decagon, said agents can then verify a bank account, check a transfer's status or complete a payment "in the moment a customer asks."
Plaid said the agents can also help resolve fraud cases, process insurance claims and move loan applications past the verification step. Plaid added that Decagon agents keep context from one session or channel to the next, so an agent can tell which details a customer has already provided and which are still needed.
On permissions, Plaid said the consumer grants access through Plaid and the agent asks for data that can speed up a resolution, such as account details or a balance lookup. Customers can later see which connections they have granted and revoke any of them whenever they choose, from either their account with that business or the Plaid Portal, the company said. Plaid said agent guardrails stay as Decagon's financial services customers already configure them, and that Decagon's agent logic is auditable.
The announcement did not give a launch date, pricing or named customers using the integration. Decagon's website lists fintech Chime among its customers. The deal resembles Plaid's partnership with AI agent company Sierra, which PYMNTS reported on August 3 lets Sierra's agents request Plaid account connections mid-conversation.

Why CEOs should care
For banks, lenders and fintechs, the pitch is fewer abandoned support chats and faster resolution. But an agent that can complete a payment is doing more than answering questions. Before switching this on, customer experience leaders should decide which actions an AI agent may take on its own, what dollar limits apply, when it must hand off to a person, and how customers confirm a payment before it goes through.
Chief information security officers and compliance teams should map the data path. Ask which account data the agent can request, where Decagon and any underlying AI model store it and for how long, how consent is recorded, and how quickly a disconnection in the Plaid Portal cuts off access. Also test whether a fraudster could talk an AI agent into verifying the wrong account or sending money to the wrong place.
General counsel and boards should settle liability in the contracts. If an agent completes a mistaken or fraudulent payment, the business, Decagon and Plaid each play a role, and the agreements should say who investigates, who reimburses the customer, and what audit logs each party must keep. Plaid frames support as shifting from a cost center to a revenue driver; measure that claim against dispute and complaint rates.
The bigger picture
Plaid is positioning its network as the permission layer between consumers' bank accounts and AI agents. In the space of a few months it has partnered with Sierra and now Decagon, two AI customer service vendors, and PYMNTS reported that OpenAI integrated with Plaid in May so ChatGPT Pro users can connect bank accounts. As more agents gain access to financial data, the terms of consent, data use and liability are becoming as important as the technology.
What’s next
Watch for named banks or fintechs deploying the Decagon integration, details on which payment types agents can initiate, and whether other AI customer service vendors sign similar deals with Plaid or its competitors. Companies evaluating these tools should run a limited pilot with read-only access before allowing agent-initiated payments, and review the results with their fraud and compliance teams.
What “Fact-checked” means
Fact-checking means testing a story’s facts against the evidence before it is published. This story went through at least two separate checks before this version was published.
- What we checked
- Its names, figures, dates, job titles, quotes and who said what were checked against the story’s sources, including its main source where it could be opened. The headline was checked for accuracy and overstatement.
- How
- A first check reviewed the whole story. If it passed, a second, skeptical check went back to the sources to look for mistakes in the most important facts. If a check flagged the story, it was edited to fix the problems found, and a separate re-check then reviewed the whole story again.
- Who
- The checks are made by our newsroom, as steps kept separate from the writing, under rules set by our editor, Hussein Mukhtar. A story the checks still flag is held for the editor, who decides whether it is fixed, published or dropped.
- If something is wrong
- “Fact-checked” does not mean error-free. If a material error is found after publication, we correct the story and add a note saying what changed. Report an error
