Is the HubSpot daily limit per app or per account?

Per account. The burst limit applies to each private app on its own, while the daily limit is shared by every private app in the same HubSpot account, so a second integration eats into the first one's day.

When does the HubSpot daily API limit reset?

At midnight in the time zone set on the HubSpot account, not in UTC. If your team works in another zone, schedule large daily jobs from the account's midnight, not your own.

What does HubSpot return when you hit the limit?

A 429 on every call until the window passes. The body's policyName says whether it was the daily or the per-second limit. HubSpot also asks that error responses stay a small share of a day's requests.

How do I see how much of the HubSpot limit is left?

Read the X-HubSpot-RateLimit headers on each response: the remaining calls in the current window and, for private apps, the daily ones. OAuth requests carry no daily headers, and search responses carry none.

HubSpot API limits by plan and app type

HubSpotHubSpot API (all public APIs; general limits)Public OAuth apps distributed through the HubSpot Marketplace: 110 requests per 10 seconds for each account that installs the app. This limit excludes the CRM Search API, and the API Limit Increase add-on does not raise it. Private (privately distributed) apps, counted per app: Free and Starter 100 requests per 10 seconds; Professional 190 per 10 seconds; Enterprise 190 per 10 seconds; any tier with the API Limit Increase add-on 250 per 10 seconds. CRM Search API: 5 requests per second per account.

Daily or monthly allowance: Private apps share one daily limit per account: Free and Starter 250,000 requests per day; Professional 625,000; Enterprise 1,000,000. Each API Limit Increase adds 1,000,000 per day on top of the base subscription, with a maximum of two increases. The daily limit resets at midnight in the account's time zone. The page gives no daily figure for public OAuth apps.
Bulk and batch: Batch endpoints: 100 records per request (for example, batch update contacts). CRM search: up to 200 records per page and 10,000 results per query; a query body can hold up to 3,000 characters, with up to 5 filterGroups of up to 6 filters each and 18 filters in total. Custom event completions batch endpoint: batches of 500.
Plans with API access: Every tier. The private-app rate-limit table lists Free, Starter, Professional and Enterprise (any Hub).
When you hit the limit: HTTP 429 on every call after the limit is exceeded. The JSON body includes status, message, errorType RATE_LIMIT, correlationId, policyName (DAILY or SECONDLY) and requestId. Error responses should stay under 5% of total daily requests, which Marketplace certification requires.
Limit headers: X-HubSpot-RateLimit-Daily, X-HubSpot-RateLimit-Daily-Remaining, X-HubSpot-RateLimit-Interval-Milliseconds, X-HubSpot-RateLimit-Max, X-HubSpot-RateLimit-Remaining (the two Daily headers are not sent on OAuth-authorized requests. X-HubSpot-RateLimit-Secondly and X-HubSpot-RateLimit-Secondly-Remaining are deprecated. Search endpoints send none of these headers.)

SalesforceSalesforce Platform API (REST and SOAP; org-wide allocations)Concurrent long-running requests (20 seconds or longer): 5 for Developer Edition and Trial orgs, 25 for production orgs and sandboxes. Requests shorter than 20 seconds have no concurrency limit. REST and SOAP calls time out after 10 minutes; query calls follow the SOQL limits instead.

Daily or monthly allowance: Total API requests per 24-hour period, counted for the whole org rather than per user. Developer Edition: 15,000. Enterprise Edition, and Professional Edition with API access enabled: 100,000 plus licenses x calls per license (Salesforce 1,000; Salesforce Platform 1,000; Lightning Platform - One App 200), plus purchased API Call Add-Ons. Unlimited and Performance Edition: 100,000 plus licenses x calls per license (Salesforce 5,000; Salesforce Platform 5,000), plus add-ons. Full Sandbox: 5,000,000. Example: an Enterprise org with 15 Salesforce licenses gets 115,000. Calls that include DebuggingHeader have their own allocation of 1,000 per 24 hours. Paid orgs in active status may go over the limit by some amount, up to a hard cap; this does not apply to trial orgs, Developer Edition or sandboxes.
Bulk and batch: Bulk API and Bulk API 2.0 calls count toward this allocation. See the salesforce-rest and salesforce-bulk rows.
Plans with API access: On by default in Enterprise, Performance, Unlimited and Developer Edition. Professional Edition can add API access as an add-on. Each user also needs the API Enabled permission.
When you hit the limit: Too many concurrent long-running requests: REQUEST_LIMIT_EXCEEDED exception code. Daily limit exceeded (REST): HTTP 403 with error code REQUEST_LIMIT_EXCEEDED. Org without API access: API_DISABLED_FOR_ORG. Call over the time limit: REQUEST_RUNNING_TOO_LONG (SOAP) or QUERY_TIMEOUT (REST).
Limit headers: Sforce-Limit-Info (api-usage=used/limit) on REST responses. Other ways to check usage: the REST /services/data/vXX.X/limits resource (Max and Remaining, accurate within five minutes); Setup > System Overview (API Usage section and 'API Requests, Last 24 Hours'); the 30-day 'API Request Limit per Month' entitlement on the Company Information page; API Usage Notifications.

SalesforceBulk API 2.0 (and Bulk API 1.0)Bulk API and Bulk API 2.0 calls count toward the org's total API request allocation (see the salesforce row).

Daily or monthly allowance: 15,000 batches per rolling 24 hours, shared between Bulk API and Bulk API 2.0. In Bulk API 2.0 only ingest jobs consume batches, and batches are created automatically. Records uploaded per rolling 24 hours: 150,000,000 for both (Bulk API 1.0 is 15,000 batches x 10,000 records). Bulk API 2.0 query jobs: 10,000 per rolling 24 hours, with 1 TB of query results per rolling 24 hours.
Bulk and batch: Bulk API 2.0 ingest: up to 150 MB of base64-encoded CSV per job (upload no more than 100 MB to allow for encoding). Bulk API 1.0: up to 10,000 records, 10 MB and 10,000,000 characters per batch. Both versions: 5,000 fields and 400,000 characters per record, 131,072 characters per field. A job can stay open up to 24 hours (Bulk API 2.0: ingest jobs only). Results can be retrieved for 7 days. Queries: maximum retrieved file size 1 GB, 20 minutes to retrieve results. Bulk API 1.0 queries return at most 15 files; with PK chunking, chunks are 100,000 to 250,000 records. A Bulk API 1.0 query has a 2-minute processing limit.
Plans with API access: Same as the Salesforce API (Enterprise, Performance, Unlimited, Developer; Professional with the API add-on).
When you hit the limit: Bulk API 1.0 queries: more than 30 attempts returns 'Tried more than thirty times'; a query taking more than 2 minutes returns QUERY_TIMEOUT. Bulk API 2.0 retries automatically: for ingest, a message that it retried more than 20 times means use a smaller upload file; for queries, more than 15 retries means add filter criteria.
Limit headers: The /vXX.X/limits/ REST resource reports DailyBulkV2QueryJobs and DailyBulkV2QueryFileStorageMB.

SalesforceREST APIUses the org-wide daily allocation and the concurrent long-running request limits in the salesforce row. A Composite, sObject Collections, sObject Tree or Composite Graph request counts as one call toward API limits. In a Composite Batch request, each subrequest counts against rate limits.

Daily or monthly allowance: Shared with the org-wide allocation (see the salesforce row).
Bulk and batch: SOQL query: up to 2,000 records returned at a time. The Sforce-Query-Options batchSize is 2,000 by default, 200 minimum and 2,000 maximum, and the requested size is not guaranteed. Composite: up to 25 subrequests, of which up to 5 can be sObject Collections or query operations. Composite Batch: up to 25 subrequests. Composite Graph: up to 500 nodes and 75 graphs per payload, maximum graph depth 15. sObject Collections create, update, upsert and delete: up to 200 records per request (up to 10 chunks when object types are mixed). sObject Tree: up to 200 records across all trees, up to five record types, up to five levels deep.
Plans with API access: On by default in Enterprise, Performance, Unlimited and Developer Edition. Professional Edition needs the API add-on.
When you hit the limit: HTTP 403 with REQUEST_LIMIT_EXCEEDED when the org's API request limit is exceeded. Request size: the combined URI and headers may be up to 16,384 bytes per REST call; a longer URI returns 414 URI Too Long, and longer URI plus headers returns 431 Request Header Fields Too Large.
Limit headers: Sforce-Limit-Info
