Salesforce Governor Limits and Other Limits
Salesforce imposes a variety of limits to ensure fair use of its resources. The limits you can use will depend on your specific Salesforce edition and the platform you are using.
These are just a few common limits that you should be aware of when designing and developing using the Salesforce platform to ensure your applications, automation, and processes are efficient within the various limits and constraints.
Governor Limits in Salesforce
Salesforce governor limits are runtime constraints and limits imposed on executing code to ensure efficient and fair use of the system resources. By implementing limits you can mitigate the degradation of the Salesforce platform by preventing resource-intensive operations. If a governor limit is surpassed or violated, the process will be paused and Salesforce will display an error.
These limits are crucial when it comes to developing your applications on the Salesforce platform. Your code should be optimized and efficient to ensure processes work within these limits. If you need to work with large sets of data regularly then your code will need to be designed accordingly and potentially implement asynchronous processing methods to prevent exceeding these limits.
Apex is Salesforce’s programming language and runs in a multienant environment. The runtime engine enforces limits on any runway Apex code or processes to ensure they won’t monopolize shared resources.
Per-Transaction Apex Limits
For each Apex transaction, these limits count. When it comes to Bartch Apex, the limits are reset for each execution of a batch of records in the execute method.
Per-Transaction Certified Managed Package Limits
Certified managed packages have passed a security review for the AppWExhange and have their own set of limits for the most per-transaction limits.
Lightning Platform Apex Limits
Restricts the number of Lightning components and the amount of client-side storage you can utilize.
Static Apex Limits
These limits apply to the default timeout of callouts in a transaction, maximum size of callout request or response, maximum SOQL query run time before Salesforce cancels the transaction, maximum number of class and trigger code units in a deployment of Apex, Apex trigger batch size, For loop list batch size and maximum number of records returned for a Btach Apex in query in Database.QueryLocator.
Size-Specific Apex Limits
These limits apply to the maximum number of characters for a class, the maximum number of characters for a trigger, maximum amount of code used by all Apex code in an org, and the method size limit.
Miscellaneous Apex Limits
These include; Connect in Apex, Data.com and Clean, Event Reports, SOQL Query Performance, and MAX_DML_ROWS limit in Apex testing.
Salesforce API Limits
API Limits and allocation are applied to Salesforce Platform SOAP and REST APIs and other APIs built on those frameworks. There are three types of limits imposed; Concurrent API Request Limits, API Timeout Limits, and Total API Request Allocations. These limits are used to maintain optimum performance.
Concurrent API Request Limits
There are limits for various types of Salesforce orgs for concurrent inbound requests (known as calls) with a duration of 20 seconds (or longer).
If the limit is exceeded, the API will return an exception code. Any new concurrent requests will not be processed until there are fewer requests than the allowed limit. Note that there is no limit on the number of concurrent requests if they are shorter than 20 seconds.
API Timeout Limits
The timeout limit is 10 minutes for REST and SOAP API calls. The timeout is set by SOQL limits. We recommend reading here for a breakdown of the specific limits.
If a request reaches a limit, the API will return a request running too long error for SOAP APIs and a query timeout exception code for the REST API.
Total API Request Allocations
There are limits for the total inbound API requests per a 24-hour period per Salesforce org.
It’s important that you monitor your API usage and keep the limits in mind. You can always set up your Salesforce org to send an email to a specific user if the number of API requests exceeds a specific percentage of your allotted amount.
Salesforce Email Limits
Each licensed Salesforce org can send a single email to a maximum of 5,000 external email addresses per day based on GMT. If you send single emails using the email author or composer in Salesforce, it won’t count towards this limit. There isn’t any kind of limit when sending single emails to leads, contacts, person accounts, and users in your org differently from the Account, Contact, Lead, Opportunity, Campaign, Case, or custom object pages.
In Lightning Experience, any email sent via an approval process instead of directly from the email composer will count towards the limit.
Frequently Asked Questions
Can we handle governor limits in Salesforce?
If a governor limit is not met, an error is raised and the process will stop. It is important to ensure your code is scalable and does not violate governor limits.
What is the limit of callout governor in Apex?
Each Apex transaction can make a maximum of 100 callouts to an HTTP request or an API call. The default timeout is 10 seconds but a custom timeout can be defined using a minimum of 1 millisecond – 120,000 milliseconds.
What is the email governor limit in Salesforce?
You can send a single email to a maximum of 5,000 external email addresses per licensed org per day (based on Greenwich Mean Time).
What are the limitations of queries in Salesforce?
- Max 100 queries in a synchronous transaction.
- Max 200 queries in an asynchronous transaction.
- Max 50 000 rows returned per transaction.
