The grant_id: One Handle for Mail, Calendar, and Webhooks

Anyone who's wired an autonomous agent into email and calendar the traditional way knows the identifier sprawl: an OAuth client ID, a refresh token per user, a Gmail-specific message ID format, a Microsoft Graph calendar ID, and a webhook subscription ID for each — all with different lifetimes, all able to break independently. Half your "integration" code is really identifier bookkeeping. Nylas Agent Accounts collapse all of that into one value. When you create an account (the feature's in beta), the response hands you a grant_id , and that single string is the handle for everything the agent does — mail, calendar, contacts, attachments, and the webhooks reporting on all of them. One ID, the whole surface Every operation addresses the same path family, /v3/grants/{grant_id}/* : POST /v3/grants/{grant_id}/messages/send # send mail GET /v3/grants/{grant_id}/messages # read the inbox GET /v3/grants/{grant_id}/threads/{thread_id} # full conversation GET /v3/grants/{grant_id}/attachments/{id}/download POST /v3/grants/{grant_id}/events # host a meeting POST /v3/grants/{grant_id}/events/{id}/send-rsvp # respond to one GET /v3/grants/{grant_id}/contacts GET /v3/grants/{grant_id}/rule-evaluations # audit trail This isn't an abstraction invented for agents — an Agent Account is literally just another grant, the same primitive used for connected Gmail and Outlook accounts. The supported endpoints reference puts it as "same endpoints, same auth, same payloads." Anything you built for connected accounts works against an agent's grant unchanged. And the resources behind the ID are real: six system folders provisioned automatically ( inbox , sent , drafts , trash , junk , archive ), a primary calendar that speaks standard iCalendar, and outbound messages capped at 40 MB total. Webhooks route by it too The inbound side completes the picture. You subscribe once at the application level, and every notification — message.created , event.updated , message.bounce_detected , and the rest

Scaling to Thousands of Agent Mailboxes

Week one: a single test mailbox on a trial domain, provisioned by hand from the dashboard. Week twelve: a fleet of agent mailboxes spread across customer domains, each sending real mail with its own quota and reputation. The API calls are the same at both scales — what changes is everything around them: how you provision, how you share configuration, and how you keep one bad sender from pausing the fleet. Here's what the path from one to thousands looks like with Nylas Agent Accounts , which are currently in beta. Provisioning is a loop, not a ceremony There's no OAuth dance to scale around. Creating a mailbox is one POST with "provider": "nylas" — no refresh token, no consent screen — so a fleet provisioner is just iteration: curl --request POST \ --url "https://api.us.nylas.com/v3/connect/custom" \ --header "Authorization: Bearer <NYLAS_API_KEY>" \ --header "Content-Type: application/json" \ --data '{ "provider": "nylas", "workspace_id": "<WORKSPACE_ID>", "settings": { "email": "agent-0042@agents.yourcompany.com" } }' Two scaling-relevant details in that request. First, the domain: one application can manage accounts across any number of registered domains, and the docs explicitly recommend splitting high-volume outbound across multiple domains ( sales-a.yourcompany.com , sales-b.yourcompany.com ) so reputation damage on one doesn't contaminate the rest. Second, the workspace_id : passing it at creation is how each account picks up its configuration, which brings us to the part that makes fleets manageable. Configure workspaces, not grants At fleet scale, per-grant configuration is a non-starter. The model here is indirection: policies and rules attach to workspaces , and every account in a workspace inherits them. One policy object — daily send quota, storage cap, retention windows, spam sensitivity — governs a thousand mailboxes, and updating it updates all of them at once. The recommended carve-up is one workspace per agent archetype: outreach agents get a work

Default Workspaces and Where New Agents Land

Every Agent Account you create lands in a workspace — the only question is whether you picked it or the platform did: curl --request POST \ --url "https://api.us.nylas.com/v3/connect/custom" \ --header "Authorization: Bearer <NYLAS_API_KEY>" \ --header "Content-Type: application/json" \ --data '{ "provider": "nylas", "workspace_id": "<WORKSPACE_ID>", "settings": { "email": "test@your-application.nylas.email" } }' That top-level workspace_id is optional, and what happens when you omit it is one of the more under-read parts of the Nylas Agent Accounts docs (the feature's in beta, so read with that in mind). Workspaces aren't cosmetic grouping — they're the carrier for every policy limit and mail rule that governs your agents. Getting placement wrong means an agent running with the wrong send quota, the wrong spam settings, or no inbound filtering at all. The placement algorithm When a new account is created, placement resolves in this order: Explicit workspace_id on the request — the account goes exactly where you said. The target workspace must belong to the same application; ownership is validated and mismatches are rejected. Auto-grouping by domain — if a workspace has auto_group enabled and its domain matches the new account's email domain, the account joins it automatically. The default workspace — everything else lands here. That third bucket is the interesting one. What the default workspace actually is Every application gets exactly one default workspace, created and managed by the platform. You can't delete it, and you can only update two of its fields: policy_id and rule_ids . Everything else is managed for you. It's easy to read "default" as "throwaway," but it's better understood as your safety net. Any account you forget to place explicitly — a quick test from the CLI, a provisioning script missing the workspace parameter — inherits whatever the default workspace carries. Which leads to a practical recommendation: attach a conservative baseline policy and

android doze kills your react native background tasks--here's why and how to fix it

android doze kills your background tasks and nobody explains why properly been building a react native app that schedules stuff to run later. worked fine every time i tested it. shipped it, and it started missing schedules. only when the phone had been sitting idle for a while. never on my desk. took me way too long to figure out what was going on so writing it up here. what happens you schedule something for 1am. check logs next morning: 01:00:00 alarm fired 01:00:02 connected (while back grounded, 2 seconds) 01:18:xx the actual send ran the connection came up fine. in 2 seconds. while the phone was back grounded. but the code that was supposed to do something with that connection ran 18 minutes later when something else woke the phone up. why doze mode freezes javascript timers. setTimeout, setInterval, any polling loop on the js thread-all frozen. but native events (connection callbacks, lifecycle events, native module bridges) keep firing. i had a setInterval checking "are we connected yet" every second. doze froze that loop. the connection came up, nobody noticed for 18 minutes because the thing checking for it was asleep. the phone could do the work. my code just couldn't tell. stuff i tried that didn't fix it foreground service — keeps the process alive but doesn't unfreeze js timers. not the problem. more setTimeout/setInterval variations, literally the thing causing it. spent two days making the problem worse. HeadlessJS dropped in without changes compiled, never ran on newer RN. lost a few hours there. the actual fix move everything off timers. put your work directly in the event handler. instead of polling to check if you're connected: js // this is frozen by doze. don't. setInterval (() => { if ( isReady ()) doWork () }, 1000 ) do this : jsconnection . on ( ' status ' , ( state ) => { if ( state === ' connected ' ) { doWork ( job ) } }) native events survive doze. timers don't. that's the whole thing. for waking up at the right time — native AlarmManager

Java Interface

today we discuss about Interface in Java. first we understand the concept with simple Analogy, Imagine you go to a shop and buy items. in a bill counter, the shop keeper care about only one thing. The customer paid the Money or not. The shopkeeper does NOT care about how you pay the money, UPI Debit Card Cash They only thing is payment paid in successfully. Here a interface acts like a Rule in billing counter. It only defines what must be done, not how it should be done. Different payment methods follow the same rule, but each one works in its own way. The shopkeeper does not need to change anything in the billing counter. No matter how the customer pays, the system works the same. so, i follow this analogy and using a example for this blog. What is Interface? (in GeeksforGeeks) An interface in Java is a blueprint that defines a set of methods a class must implement without providing full implementation details. It helps achieve abstraction by focusing on what a class should do rather than how it does it. Interfaces also support multiple inheritance in Java. A class must implement all abstract methods of an interface. All variables in an interface are public, static, and final by default. Interfaces can have default, static, and private methods first create a interface file Payment.java public interface Payment { void pay ( int amount ); } here we create a method but not defined that method This is the shop rule. “Anyone wants to pay must follow one rule → pay the amount.” The shop does not explain how you pay, only thing is you must pay. next we create another file for Different Customers, class CardPayment implements Payment { public void pay ( int amount ) { System . out . println ( "Paid ₹" + amount + " using Card" ); } } class UpiPayment implements Payment { public void pay ( int amount ) { System . out . println ( "Paid ₹" + amount + " using UPI" ); } } class CashPayment implements Payment { public void pay ( int amount ) { System . out . println ( "Paid ₹" +

Big Tech’s desperate last push at AI regulation

For months, Big Tech's Washington lobbyists have chased after the holy grail of pro-AI legislation: preemption. This would be a comprehensive federal law, passed in Congress and signed by the president, applying one set of AI rules across the entire country and overriding the legally messy state-by-state approach to regulation. For months, lobbyists have run […]
