Transfer from one profile to another - Rails and Stripe -

i write first time , glad if me.

i create rails app stripe payment , have 2 type of customers.

when customer1 logs system, needs fill payment credentials form(cardholder, cvc, cart number). form information , stripe.js generated card_token use token create customer , save database.

when customer2 logs system, use stripe connect connect system customer2 stripe account.

how can transfer money customer1 customer2`s account.i use

stripe.api_key = platform_secret_key stripe::charge.create({   :amount => 1000,   :currency => "usd",   :source => {token},   :destination => {connected_stripe_account_id} }) 

and try curl request:

curl https://api.stripe.com/v1/charges \    -u {platform_secret_key}: \    -d customer={stripe_customer_id} \    -d amount=1000 \    -d currency=usd \    -d destination={connected_stripe_account_id} \    -d application_fee=200 

but both give me error:

"type": "invalid_request_error",     "message": "invalid api key provided: {**_****_********************xuw}"
