DETERMINING DIRECTIONS FOR DELIVERING A PRODUCT FROM A VENDOR ASSOCIATED WITH A VENUE TO A USER WITHIN THE VENUE

1 . A method comprising:

receiving a request for a product at an online system associated with a venue from an application associated with the online system executing on a client device, the request identifying the product and a physical location of the client device;

selecting a vendor associated with the venue to fulfill the request for the product based on the service and information maintained by the online system identifying products provided by vendors associated with the venue;

transmitting the request to the selected vendor;

selecting a delivery person associated with the selected vendor to provide the product, the delivery person associated with an additional client device;

determining directions from a physical location of the additional client device to the physical location of the client device;

generating an interface identifying the physical location of the additional client device, the physical location of the client device, and the directions from the physical location of the additional client device to the physical location of the client device; and

transmitting the generated interface to the additional client device for presentation to the delivery person.

2 . The method of claim 1 , wherein determining directions from the physical location of the additional client device to the physical location of the client device comprises:

determining an estimated time from the physical location of the additional client device to the physical location of the client device.

3 . The method of claim 2 , wherein the generated interface further identifies the estimated time from the physical location of the additional client device to the physical location of the client device.

4 . The method of claim 1 , further comprising:

identifying a change in the physical location of the client device;

determining modified directions from the physical location of the additional client device to the changed physical location of the client device;

modifying the interface to identify the changed physical location of the client device, the physical location of the additional client device, and the modified directions from the physical location of the additional client device to the changed physical location of the client device; and

transmitting the modified interface to the additional client device for presentation to the delivery person.

5 . The method of claim 1 , further comprising:

identifying a change in the physical location of the additional client device;

determining modified directions from the changed physical location of the additional client device to the physical location of the client device;

modifying the interface to identify the physical location of the client device, the changed physical location of the additional client device, and the modified directions from the changed physical location of the additional client device to the physical location of the client device; and

transmitting the modified interface to the additional client device for presentation to the delivery person.

6 . The method of claim 1 , wherein transmitting the request to the selected vendor comprises:

identifying a threshold distance from a physical location of the selected vendor;

transmitting the request to the selected vendor in response to a physical location of the client device obtained by the online system being less than the threshold distance and the physical location of the selected vendor.

7 . The method of claim 6 , wherein identifying the threshold distance from the physical location of the selected vendor comprises:

determining the threshold distance from the physical location based on the product identified in the request.

8 . The method of claim 1 , wherein transmitting the request to the selected vendor comprises:

transmitting the request to the selected vendor;

transmitting an instruction to fulfill the request to the selected vendor in response to the online system determining a physical location of the client device obtained by the online system is less than the threshold distance.

9 . A computer program product comprises a computer readable storage medium having instructions encoded thereon that, when executed by a processor, cause the processor to:

receive a request for a product at an online system associated with a venue from an application associated with the online system executing on a client device, the request identifying the product and a physical location of the client device;

select a vendor associated with the venue to fulfill the request for the product based on the service and information maintained by the online system identifying products provided by vendors associated with the venue;

transmit the request to the selected vendor;

select a delivery person associated with the selected vendor to provide the product, the delivery person associated with an additional client device;

determine directions from a physical location of the additional client device to the physical location of the client device;

generate an interface identifying the physical location of the additional client device, the physical location of the client device, and the directions from the physical location of the additional client device to the physical location of the client device; and

transmit the generated interface to the additional client device for presentation to the delivery person.

10 . The computer program product of claim 9 , wherein determine directions from the physical location of the additional client device to the physical location of the client device comprises:

determine an estimated time from the physical location of the additional client device to the physical location of the client device.

11 . The computer program product of claim 10 , wherein the generated interface further identifies the estimated time from the physical location of the additional client device to the physical location of the client device.

12 . The computer program product of claim 9 , wherein the computer readable storage medium further has instructions encoded thereon that, when executed by the processor, cause the processor to:

identify a change in the physical location of the client device;

determine modified directions from the physical location of the additional client device to the changed physical location of the client device;

modify the interface to identify the changed physical location of the client device, the physical location of the additional client device, and the modified directions from the physical location of the additional client device to the changed physical location of the client device; and

transmit the modified interface to the additional client device for presentation to the delivery person.

13 . The computer program product of claim 9 , wherein the computer readable storage medium further has instructions encoded thereon that, when executed by the processor, cause the processor to:

identify a change in the physical location of the additional client device;

determine modified directions from the changed physical location of the additional client device to the physical location of the client device;

modify the interface to identify the physical location of the client device, the changed physical location of the additional client device, and the modified directions from the changed physical location of the additional client device to the physical location of the client device; and

transmit the modified interface to the additional client device for presentation to the delivery person.

14 . The computer program product of claim 9 , wherein transmit the request to the selected vendor comprises:

identify a threshold distance from a physical location of the selected vendor;

transmit the request to the selected vendor in response to a physical location of the client device obtained by the online system being less than the threshold distance and the physical location of the selected vendor.

15 . The computer program product of claim 14 , wherein identify the threshold distance from the physical location of the selected vendor comprises:

determine the threshold distance from the physical location based on the product identified in the request.

16 . The computer program product of claim 9 , wherein transmit the request to the selected vendor comprises:

transmit the request to the selected vendor;

transmit an instruction to fulfill the request to the selected vendor in response to the online system determining a physical location of the client device obtained by the online system is less than the threshold distance.
