The Xrm.WebApi is one of the important modules in Dynamics 365 that allows the CRM users to interact and perform operations with Dynamics 365 platform by sending and receiving data via web services. One of the most important function of Xrm.WebApi is retrieveMultipleRecords, which allows developers to retrieve a collection of records from Dynamics 365 in a single API call, increasing efficiency and reducing the number of requests needed to retrieve large amounts of data.
The Xrm.WebApi.retrieveMultipleRecords method takes two parameters: the entity logical name and an OData query.
The entity logical name is the name of the entity that you want to retrieve records for. For example, if you want to retrieve all accounts, you would pass “account” as the entity logical name.
The OData query is used to filter the records that are returned. This can be as simple as a query that returns all records, or it can be a more complex query that includes filtering and sorting. For example, to retrieve all active accounts where the name starts with “A”, you would pass the following query: “?$filter=statecode eq 0 and name startswith ‘A'”.
Once the retrieveMultipleRecords method is called, it will return a promise that resolves to a collection of records. You can then use the returned data to display the records in a custom application or to perform additional operations on the data.
Here is an example of how you can use the Xrm.WebApi.retrieveMultipleRecords method to retrieve all active accounts:
