/**
 * <p>Merges two users having different <code>IdentityId</code>s, existing in the same
 *          identity pool, and identified by the same developer provider. You can use this action to
 *          request that discrete users be merged and identified as a single user in the Cognito
 *          environment. Cognito associates the given source user (<code>SourceUserIdentifier</code>)
 *          with the <code>IdentityId</code> of the <code>DestinationUserIdentifier</code>. Only
 *          developer-authenticated users can be merged. If the users to be merged are associated with
 *          the same public provider, but as two different users, an exception will be
 *          thrown.</p>
 *          <p>The number of linked logins is limited to 20. So, the number of linked logins for the
 *          source user, <code>SourceUserIdentifier</code>, and the destination user,
 *             <code>DestinationUserIdentifier</code>, together should not be larger than 20.
 *          Otherwise, an exception will be thrown.</p>
 *          <p>You must use Amazon Web Services developer credentials to call this
 *          operation.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { CognitoIdentityClient, MergeDeveloperIdentitiesCommand } from "@aws-sdk/client-cognito-identity"; // ES Modules import
 * // const { CognitoIdentityClient, MergeDeveloperIdentitiesCommand } = require("@aws-sdk/client-cognito-identity"); // CommonJS import
 * // import type { CognitoIdentityClientConfig } from "@aws-sdk/client-cognito-identity";
 * const config = {}; // type is CognitoIdentityClientConfig
 * const client = new CognitoIdentityClient(config);
 * const input = { // MergeDeveloperIdentitiesInput
 *   SourceUserIdentifier: "STRING_VALUE", // required
 *   DestinationUserIdentifier: "STRING_VALUE", // required
 *   DeveloperProviderName: "STRING_VALUE", // required
 *   IdentityPoolId: "STRING_VALUE", // required
 * };
 * const command = new MergeDeveloperIdentitiesCommand(input);
 * const response = await client.send(command);
 * // { // MergeDeveloperIdentitiesResponse
 * //   IdentityId: "STRING_VALUE",
 * // };
 *
 * ```
