# Expert Professional Services Source: https://developer.nylas.com/docs/support/professional-services/ Some integration hurdles are faster to clear with an engineer beside you. Nylas Expert Professional Services are focused, live sessions that target one specific technical problem, from passing Google's OAuth audit to scaling your webhook layer, so your implementation reaches production sooner. ## What's included Professional Services covers six focused offerings, each aimed at a common integration hurdle. You can book one offering or combine several into a single engagement. Every offering is delivered in two 45 minute sessions, scoped to a concrete outcome: a passed verification review, a validated architecture, a working OAuth app, or a hardened notification layer. ### Google verification review Pass your Google OAuth audit on the first attempt. A Nylas engineer runs a sanity check of your production environment and YouTube demo video against the requirements Google reviewers look for, which helps you avoid repeated rejections. Pair this with the [Google verification and security assessment guide](/docs/provider-guides/google/google-verification-security-assessment-guide/). ### Architecture design and workflow review A deep dive into your specific email or scheduling workflows. You get practical feedback and best-practice mapping so your backend logic stays efficient and your user experience holds up as you grow. It's most useful before you commit to a design you'll build on for months. ### Go-to-market review An audit of your current onboarding and sign-in flows, with guidance on friction-minimal [authentication](/docs/v3/auth/) and engagement strategies that turn first-time visitors into active, authenticated users. ### Provider OAuth app creation Collaborative setup of your Microsoft Entra, Google Cloud, or Zoom apps from scratch. The session helps you sidestep the misconfigurations in testing mode or scope selection that cause breaking changes later in development. ### Notification and webhook best practices A walkthrough of designing and scaling your [notification layer](/docs/v3/notifications/), including webhooks and Pub/Sub. You'll cover retry logic, high concurrency, and the failure handling that keeps a real-time data layer stable in production. ### Ad-hoc expert consultation Open consultation with a Nylas expert on any topic. Bring a question about your implementation and get practical feedback grounded in real-world experience across many integrations. ## Why use Professional Services Professional Services gives you direct access to engineers with deep domain expertise, working live on your specific problem. They help you catch gotchas in your auth and notification layers early. A focused 90 minutes with an engineer can replace days of trial and error before a launch. ## How sessions work Each engagement runs over email and video, with a timebox of 10 business days. It includes two 45 minute sessions, scheduled around your timeline so the work lands ahead of your release. You can book one offering on its own or bundle several into the same engagement. ## Request a session To book Professional Services, [contact the Nylas team](https://www.nylas.com/contact-professional-services/?utm_source=docs&utm_content=professional-services) and describe the offerings you're interested in.
