client := plaid.NewClient("test_id", "test_secret", plaid.Tartan) // POST /auth postRes, mfaRes, err := client.AuthAddUser("plaid_test", "plaid_good", "", "bofa", nil) if err != nil { fmt.Println(err) } else if mfaRes != nil { // Need to switch on different MFA types. See https://plaid.com/docs/api/#auth-mfa. switch mfaRes.Type { case "device": fmt.Println("--Device MFA--") fmt.Println("Message:", mfaRes.Device.Message) case "list": fmt.Println("--List MFA--") fmt.Println("Mask:", mfaRes.List[0].Mask, "\nType:", mfaRes.List[0].Type) case "questions": fmt.Println("--Questions MFA--") fmt.Println("Question:", mfaRes.Questions[0].Question) case "selections": fmt.Println("--Selections MFA--") fmt.Println("Question:", mfaRes.Selections[1].Question) fmt.Println("Answers:", mfaRes.Selections[1].Answers) } postRes2, mfaRes2, err := client.AuthStepSendMethod(mfaRes.AccessToken, "type", "email") if err != nil { fmt.Println("Error submitting send_method", err) } fmt.Println(mfaRes2, postRes2) postRes2, mfaRes2, err = client.AuthStep(mfaRes.AccessToken, "tomato") if err != nil { fmt.Println("Error submitting mfa", err) } else { fmt.Println(mfaRes2, postRes2) } } else { fmt.Println(postRes.Accounts) fmt.Println("Auth Get") fmt.Println(client.AuthGet("test_bofa")) fmt.Println("Auth DELETE") fmt.Println(client.AuthDelete("test_bofa")) }Exchange a Plaid Link public_token for an API access_token:
client := plaid.NewClient("test_id", "test_secret", plaid.Tartan) // POST /exchange_token postRes, err := client.ExchangeToken(public_token) if err != nil { fmt.Println(err) } else { // Use the returned Plaid API access_token to retrieve // account information. fmt.Println(postRes.AccessToken) fmt.Println("Auth Get") fmt.Println(client.AuthGet(postRes.AccessToken)) }With the Plaid + Stripe ACH integration, exchange a Link public_token and account_id for an API access_token and Stripe bank_account_token:
client := plaid.NewClient(CLIENT_ID, SECRET, plaid.Tartan) // POST /exchange_token postRes, err := client.ExchangeTokenAccount(public_token, account_id) if err != nil { fmt.Println(err) } else { // Use the returned Plaid access_token to make Plaid API requests and the // Stripe bank account token to make Stripe ACH API requests. fmt.Println(postRes.AccessToken) fmt.Println(postRes.BankAccountToken) }// GET /categories/13001001 category, err := plaid.GetCategory(plaid.Tartan, "13001001") if err != nil { fmt.Println(err) } else { fmt.Println("category", category.ID, "is", strings.Join(category.Hierarchy, ", ")) }
