In the mobile application world, going to market quickly with the core features your users need is critical. That's why we created the Nylas API, to help developers build the mobile application of their dreams without having to worry about the communications layer. 

<p>Developers building mobile applications use the Stripe API for payments, the Twilio API for SMS, and the Nylas API for email, calendar and contacts.&nbsp;<span>Nylas's&nbsp;</span><a href="https://www.nylas.com/email-api">email</a><span>&nbsp;API,<span>&nbsp;</span></span><a href="https://www.nylas.com/sync-contacts">contacts</a><span>&nbsp;API, and<span>&nbsp;</span></span><a href="https://www.nylas.com/calendar-sync">calendar</a><span><span>&nbsp;</span>API power Android and iOS applications for companies like Voiply (the cloud-based phone system) and Haystack CRM.&nbsp;</span></p>
<p>So what can you build with the Nylas API? Let's dive in.<span style="background-color: transparent;">&nbsp;</span></p>
<p><span style="background-color: #ffffff; color: #6a6e6a;"><strong><span style="font-family: 'Avenir Next LT W04 Regu1437496', sans-serif; font-size: 22px; text-align: center;">Scheduling &amp; Calendar Sync for Android and iOS applications</span></strong></span></p>
<p>Ensure the end-users of your mobile app never miss a meeting by powering your application with calendar sync. The Nylas Calendar API connects to 100% of calendar providers, enabling scheduling and calendar sync features between your mobile application and your user's specific calendar provider (Google Calendar, Exchange Calendar, Outlook.com Calendar, and the rest).&nbsp;</p>
<p><a href="https://www.haystackcrm.com/">HaystackCRM</a>,<span style="background-color: transparent;">&nbsp;a mobile-first CRM for contact and sales pipeline management, built scheduling &amp; calendar sync into their application with the Nylas API.</span></p>
<p>Now users can choose to connect their calendar accounts to view and schedule events within HaystackCRM.&nbsp;</p>

<p>(Haystack Calendar Sync)</p>
<p><strong style="background-color: transparent; color: #6a6e6a; font-size: 18px;">Build Calendar Sync in Weeks, Not Months</strong></p>
<ul>
<li>In just one internal hackathon, it took one engineer a single day to build out their powerful scheduling tool by simply using the Nylas Calendar API as their framework. The result was a powerful scheduling tool that united all users’ calendar synching, regardless of platform.</li>
</ul>
<p><strong style="background-color: transparent; color: #6a6e6a; font-size: 18px;">Feature-Rich Calendar Functionality</strong></p>
<ul>
<li>They also built out feature-rich functionality that provided everything a user would want in to schedule meetings. Users can fully create, read, update, and delete calendar events in real time. As a result, all users are able to quickly book and cancel appointments, set appointment reminders, and even view cross-platform productivity analytics — all within the iOS app.</li>
</ul>
<p><strong style="background-color: transparent;">Key Takeaway:</strong><span style="background-color: transparent;"> With a powerful calendar API, your team gets a headstart building other core features while reducing devops hours.</span><span style="background-color: transparent;">&nbsp;</span></p>
<p><strong style="color: #6a6e6a; font-size: 22px; background-color: transparent;"><span style="color: #6a6e6a; background-color: #ffffff;">Email Sync on Android for iOS Devices</span></strong></p>
<p>HaystackCRM also uses the Nylas API to remove friction from their CRM-to-email integration. They needed to find a way to integrate their CRM within Office365, Outlook.com, Exchange, and IMAP email providers in a way that scaled with their business.&nbsp;<span>Using the Nylas API has given HaystackCRM more options of email management beyond the initial offering. Features powered by the Nylas API allow HaystackCRM users to maintain a level of comfort of using previous email addresses, email clients and calendars while moving forward with HaystackCRM.</span></p>

<p><strong style="background-color: transparent; color: #6a6e6a; font-size: 18px;">Two-Way Email Sync</strong></p>
<ul>
<li>The Nylas email API provides seamless two-way email, calendar, and contacts sync between a single user’s inbox and the customer’s CRM. From there, users could compose and send emails from within the app — saving a wealth of time by minimizing the need for context switching and eliminating any need for manual data entry between the CRM and the app.</li>
</ul>
<p><strong style="background-color: transparent; color: #6a6e6a; font-size: 18px;">Group Email Accounts</strong></p>
<ul>
<li><span style="background-color: transparent;">The customer’s app was also better able to create more sophisticated email-to-CRM synching features. For instance, with the aid of the Nylas email API, CRM users could great group email accounts to enable quicker and more efficient collaboration across the team. For instance, if a team member was on vacation or out sick, any team member can simply log into the app and see recent customer interactions right within the app.</span></li>
</ul>
<p><strong>Key Takeaway</strong>: While there is often a great deal of complexity when it comes to developing features for cross-platform CRM integrations, an intuitive API allows developers to build powerful, new CRM features on the fly.</p>
<p><strong style="color: #6a6e6a; font-size: 24px; background-color: transparent;"><span style="color: #6a6e6a;">Contacts Sync for Android and iOS apps</span></strong></p>

<li>The Nylas Contacts API syncs profile information from user's contacts books to mobile applications and back. If a profile photo, email address, physical address, phone number, or any other critical information is updated in the user's address book, your mobile application is updated immediately as well.</li>
</ul>
<p><strong style="background-color: transparent; color: #6a6e6a; font-size: 18px;">Quick and Friction-Free Integration</strong></p>
