Connect Paymo to InvoiceXpress
When New Client fires in Paymo, your agent runs Create Invoice in InvoiceXpress. Describe the whole flow and it is built, tested on every scenario and kept running.
What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.
Build solutions, not workarounds.

https://mcp.apiant.aiOne connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser.

Questions
Paymo and InvoiceXpress, answered
What can start an automation from Paymo?
Any of Paymo's 16 triggers in the catalog, including New Client, New Client Contact, New Estimate and New Expense. Describe the moment in plain language and your agent picks the right one.
What can your agent do in InvoiceXpress when something happens in Paymo?
Any of InvoiceXpress's 32 actions, including Create Invoice, Create Invoice-Receipt, Update estimate and Update Invoice. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from InvoiceXpress to Paymo?
InvoiceXpress has no triggers in the catalog today, so automations start in Paymo. If you need the other direction, ask: your agent reads InvoiceXpress's API documentation and adds it.
Do I have to build a connector for Paymo or InvoiceXpress?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
Can my AI client use Paymo and InvoiceXpress without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
