Key capabilities include declaring and managing nexus across states, listing and submitting VAT returns, preparing 1099 forms, and checking shipment compliance for regulated goods like wine. Avalara indexes 12 workflows on APIs.io, including a 'Calculate and Commit a Transaction' flow for charging correct tax at checkout. It's a hosted, self-serve service, so you call its endpoints rather than running anything yourself. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What API operations does Avalara provide for managing sales tax nexus across states? Avalara exposes nexus management through its AvaTax API: GET /api/v2/companies/{companyId}/nexus lists declared nexus, POST to the same path declares nexus in a new state, and POST/GET on /nexus/{nexusId}/parameters add or show details like flagging a remote seller status. These calls let a company track where it has an obligation to collect tax. _Developers wiring up tax compliance can track API changes like these on daily.dev._ ### Can Avalara check if a wine shipment is allowed before it ships to a customer? Yes, Avalara's Regulatory Compliance Management APIs verify whether a direct-to-consumer shipment, such as wine, complies with state rules before it ships. The GET .../shipment/verify endpoint checks compliance, while PUT .../shipment/registerIfCompliant checks and registers the shipment in one step, and DELETE .../shipment/registration removes an order from tracked shipping volume limits. _Teams building regulated e-commerce shipping flows can follow API updates like this on daily.dev._ ### How do I file a VAT return using Avalara's API? Avalara's Tax Reporting & Compliance API handles VAT return filing through three calls: GET /returns lists VAT returns still waiting to be filed, GET /returns/{returnId} lets you review a return before submission, and POST /returns/{returnId}/submit files the finalized return with the tax authority. _Anyone automating VAT filing workflows can track API and compliance tooling updates on daily.dev._ ## Similar posts on daily.dev - [AWS Marketplace streamlines VAT payment for deemed supply transactions](https://daily.dev/posts/aws-marketplace-streamlines-vat-payment-for-deemed-supply-transactions-kmulnj1ak) · AWS · 2 upvotes · 0 comments - [Numeral raises $100m Series C for AI sales tax compliance](https://daily.dev/posts/numeral-raises-100m-series-c-for-ai-sales-tax-compliance-oof5grrcw) · The Next Web · 0 upvotes · 0 comments - [My bookkeeping runs on code now.
